Title: SMason's 78 GMC K25 4x4 Build Thread
Post by: Scott M on April 09, 2015, 01:37:19 pm
Howdy Everyone!

Want to start a thread on my truck like everyone else...I have been working on this truck since Feb 2014  It has been a slow process for me and this is my first truck of its kind. heres a little about the truck

Bought it off of craigslist for 1600 back in August 2013 It was all stock had surface rust on the frame, had holes all in the fenders hood and bed, it ran good drove descent and pretty much everything worked for the most part the inspection went out in sept of 13 and took it in and it passed.  I drove it around for awhile took it to the beach often and then I got my income tax check beginning of the year 2014 and decided to put a 6 inch suspension lift on it.

here are some pics before the lift during and after.....

Then on the maiden voyage of the lifted truck to the beach I ended up locking up the motor..the motor had to have blown a seal because there was oil all over the tranny and transfer and it burned up.  I had it towed home.

I just so happened to have a ZZ4 crate motor sitting on an engine stand that I had bought to throw in a 98 jeep TJ I had but ended up trading the jeep so I had the motor sitting.  The ZZ4 the previous owner had it in a YJ rock crawler and was running a TBI on it.  I decided that instead of keeping the TBI i would convert it back to Carb to throw in the truck.  I bought a new GM performance intake that originally came with it and bought a Holley 670CFM Street Advenger Carb to go on it from jegs....

I then began the process of pulling the old motor and here are some pics...

After I started looking more into the ZZ4 and taking the intake off I flipped it over to check the main bearing tolerances and found one bearing was scored or whatever you want to call it pretty good so then I made the decision to take it to the machine shop/performance engine guy in town and he fixed it up pretty darn good for the price I paid.  He tested block and did the work he needed to do to clean it up, new cam bearings, main bearings, turned the crank, felpro rebuild kit, tested heads they were warped so he decked the heads and did a valve job on it for free, new piston rings and high volume oil pump. and i think thats about it and put it completely back together cost me $998 out the door

here are some pics after the rebuild...

Then it was time to start putting the motor in bought new motor mounts and ended up taking the bed off and bedlinning the frame after I killed the rust with OSPHO and sanded it down best I could...  I also realized that all my body bushings were shot so I bought a new set of bushings and decided that while I was replacing those that I would go ahead and put a 2 inch body lift on it...

then i determined that the inner fenders and front fenders were too far gone so I bought new aftermarket ones and found a used bed in better shape than mine on craigslist and went and picked it up in Houston, tx.

bought new holley HV mech fuel pump, hooker headers, SS braided Tranny Cooler lines all kinds of stuff, pretty much alot of new stuff lol

here are some pics from all this..,..

All this has been over the past year motor blew up end feb 2014 motor rebuilt summer 14 and been trying to get it all together since then

I ordered a clamp on exhaust kit to get me by...turns out i dont like it so ima take it to the muffler shop get them to weld it up for me, new batter tray box, had to switch the gas tank from the passenger side to the driver after i realized the bed I bought it was on the other side

Recently drug it over to victoria bout a 72 mile trip pulled it with my ford had been doing final touches to it and breaking in the motor still i guess you could say prolly put about 20 miles on it running. I have installed after market guages for coolant temp volt and oil pressure, aftermarket Tach,

Putting a radio and small sound system in it now, I got a JVC radio, a 10inch pioneer shallow mount sub and box, pioneer 900 watt amp and 4 guage amp wiring kit,

Bought a new rear driveshaft from Tom Woods and upgraded the output yoke from the 1310 series to the 1350 series happy with all that

NOW here are the problems

I am still currently figuring out the windshield wiper switch problem I am having, the front driveshaft I just dont think is going to work and the emergency brake rear cable is cut (my stupid mistake)

with it lifted I am going to have to figure out how to rig them up so they work for inspection still dont know what to do....

Welcome from Northern Illinois. Nice truck and great work on the mods. Are those Ground Hawgs or Grand Prix's on your truck? When I was younger my buddy had some Grand Prix brand tires, I believe 40's on his Blazer. They were the cheaper alternative to Ground Hawgs. It is also nice to see the all spring lift instead of blocks in the rear. Keep up the good work.

Well made small progress on the truck yesterday...here in mid-south tx we have been getting hammered with rain for the past several weeks 50-70% all week and last too so havnt been able to do a whole lot till yesterday and it still rained about 3pm lol

I got the rear bumper holes drilled and the rear bumper mounted again had to raise it up and drill new holes because of the 2" body lift it turned out ok this is as high as it will mount with my current set up.

then I got my new pioneer sub in from ebay this past monday and the new box from walmart.com  the box is 5" wide top to bottom it pushes on the seat a little bit at the top but since I have it in the passanger side its not that bad.... did have to make the hole bigger for the pioneer shallow sub about a 1/4" all the way around.

weather depending this weekend will determine if I will be able to mess with the emergency brakes some more....

Was able to completely finish wiring up the radio...did not use the stock harness ran all new wires to the ground block, ignition fused and hot fuse in the fuse block along with new speaker wires...

I installed two new 6x9 speakers behind the seat and hooked up the sub, man it sounds really good! Perfect for the truck im glad i went with a 10" sub its all i will need!

I also messed with the praking brakes and i am able to put the truck in drive and get it to hold....reverse thats a different story it creeps still but them cables are so dang tight that idk if it has anymore to give....

I think its time to redo the drum brakes and replace the emergency brake cables instead of having them rigged like i do....plan is to take it try and see if i can get them to pass it on inspection and then hopefully replace the brakes in the drum in the few months got my fingers crossed being in texas and on the coast we have no elevation changes here and the larking brake is used very rarely!

I took the truck in this morning to get an inspection to an old school service station and it passed the state safety inspection!! Heck ya! im pumped now just have to get it registered with the new texas two step program! one step down!

Left to do too get it fully capable on and off road is to fix my front driveshaft problem

I plan on changing the oil again even though I only have about 50 miles on it since the rebuild.

I have read all about the ZZ4 break in and stuff and I should be pretty good to go I believe supposidly with the roller cam the motor breaks in within the first 20 min or so along with all the other things like the rings and main bearings I did the graduale pulls rolling from like 10mph up to 45 or 50 with half and then 3/4 throttle so hopefully this is all I have to do... I plan on not getting crazy for the first 500-1000 miles but the amount of miles I actually drive the thing this might take forever lol Im going to drive it to work everyday for the nxt couple of weeks to help build up miles (5 mile drive in city traffic) should keep from driving at a constant rpm and stuff and drive it around town hopefully i can get to about 500 miles in the next 2 weeks, I might make an extended trip to the other side of town after work in order to gain more miles that would put me at about a 25 mile trip per day....Ima have to make more loops then that to get to 500 in two weeks lol Ill just have to do the drive twice instead of 1 time no big deal hopefully lol

anybody know where you can buy one of these or what it is actually called? the throttle cable screws into it at the transfer case and i believe there might be different ratios you can buy to account for tire size? Anybody ever messed with it? or replaced and found original or aftermarket setup?? Mine is super loose? has alot of play in it...

That is a speedometer ratio adapter.
It should be tight to the T-Case.

Is your speedo working?
If so is it indicating the correct speed?

If yes to both just snug up the adapter and you are good to go.


Nice truck.
Nicer white Lab. Looks just like our white Lab Charlie.

I replaced the speedo cable and it worked for a bit, then it just stopped, I got around to looking at it and the cable was all twisted up at that very end, so they are cheap enough I was going to replace it again, ill try tightning down on that piece today to see if it helps to not mess up the new cable...

ahh yea hes a smart dog and good one too! I have a funny video of him climbing a palm tree to get a squirrel pretty funny! squirrel 1 dog 0 lol

The ends of your speedo cables should have square ends about an inch long and you want to make sure both square ends are fully seated. Light touch and a little wiggling to get the cable ends fully seated.

Your speedo ratio adapter looks like it is not tight to the transfer case. I can see oil leaking in your picture. I had the same problem.

Got to love Labs.
We have three. A white, black, and blond.
Two of the three want nothing more than to hang out while I work on my truck.

well I hooked up the new cable, the adapter was pretty darn tight but I got on it a tad bit more. the part that is loose is not at the nut its about a 1/4" up at a joint towards the cable.  All i can figure is it is just plumb worn out. 

I towed the rig to bay city (73 miles) and left it over there (closer to the beach back home).  I met with my cousin cause he said he had a driveshaft that might work for the front, so i looked at it and its too short by a long shot....so i have learned that apparently they made two versions a long and short....

he also had some goodies from a parts truck that i did not know he had bought, its an 80 with red interior so for the most part identicle he said he got what he wanted motor tranny and axles and whatever I wanted he would make a heck of a deal....I said shoot yea let me get a list together haha. 

Thinking about taking the dash(perfect condition) 205 transfercase, hood latch, front and side marker lenses, front headlight retainer rings, crossmember, heater switches, he said anything is fair game except for the cab itself but everything inside is game too

Try taking the adaptor out and screwing your speedo cable directly to the transfer case.
My speedo & odo didn't work, took the adaptor out of the equation and problem solved (yeah it's not accurate but I don't need it to be, just need the odo to work)

Well parts and accessories will have to come to a stand still for awhile, only thing I am waiting on is to meet up with a guy for some front driveshafts, I will do what it takes to get them on, I will also put on the throttle return spring bracket I bought to move the springs to the front. 

I have to save up to get alot of work done on my daily driver about 3500 worth of stuff so it will be awhile till I have money to spend on the ole gmc sadly.  at least i got it to a point where it is drivable

Post by: Scott M on May 18, 2015, 02:38:33 pm
I found a driveshaft (long style) out of a 85 the guy said so i put it up where it goes see if the length was going to be close enough and seems like it will work.  I took it to the driveshaft place here in town cause the ball and socket deal in the dbl cardone had failed. Getting all new u-joints, ball and socket rebuild kit and trimming a tad around the double joint for more angle gonna run me $150 thats with USA u-joints i forgot if he said neapco or spicer i dont remember greasable. I figured thats not too bad i guess and told him to do it.  He said he will have it done same day (today) which is great cause ill be needing the 4x4 for the beach this weekend. 

as for the speedo cable and adapter put the new cable on and tightened up a bit on the nut (what i could) and so far so good.  maybe the first cable wasnt seated properly.

Thank you,  There is way more than what i posted mainly cause I did not start this thread while doing it. there would have been alot more pics as well as more detailed notes of what all is new.  Basically in my mind some of the last things i need to make this truck be completed in my mind is a new cowl hood then i can get the thing painted. need new rear bumper would prefer a ranch hand type  bumper, new grill for the front, new dash or dash cover, umm little things but paint job is def high on the list.


I did manage to pick up a new to me toolbox for the truck.  Its the same one i have in my f350 and i like it alot.  found it on craigslist paid 60 bucks!!! i think its a heck of a deal!  here some pics of it up in the bed.  only bad part is you cant access it without climbing up in the bed haha! but should really be nice especially for the tools and fluids i want to carry just cant carry them without one and have them out of the way.

Got the front set up on for the throttle return springs and this is like night and day difference.  My pedal was stiff and hard and seemed like i was always fighting it.  Put the front set up on and the supplied "light" springs and it no longer has a stiff pedal and has quicker throttle response have noticed the gas gage goes down faster tho hahahahaha :o

So im on to the latest little project for this truck....

I had a buddy hit me up today asking if i was interested in a ranchhand full replacement bumper for my f350. the condition is about a 3 to 4 out of 10 the powdercoating peeling off everywhere and some rust cause it came from a truck up north.  i then immediatly realized i didnt want to spend the money to make it nice enough to put it on my f350 and started dreaming about putting it on the gmc...

so we talked it all out and i convinced myself of what all i would have to do in order to make it look good and mount up to the gmc.

the first priority is to get all the paint off and either get it media blasted or sanding and grinding it.  Prolly sand and grind cause I would have to pay to get the other option.  Then I am going to measure it all out and mock it up and start trimming and cutting it to the look that i have in my head. make the brackets needed to mount it to the frame.  then coat it with a bedliner and call it a day.

I think it might turn out looking good and i plan on beefing it up in the middle in order to mount a winch.  has anybody else done anything similar? Also I was told to ask if there are already a generic type bracket that somebody makes? In my head I know about what its going to take to make a bracket hopefully it all works out.

What yall think? I know its going to be work and alot of it but I think it will be worth it especially what little i will have in it.  I have a pic of it but will have to post it later.

Post by: Scott M on August 24, 2015, 10:41:36 pm
Its a little hard to imagine but i have a really good idea i guess ill just have to go with it. Im going to cut the wrap around parts off and make it where it sits flat across the front.  The bars that wrap around to protect headlights will be cut and i will either weld a pipe the same size that cuts them off similiar to almost a bull bar look but still let them come down at an angle haha its hard to talk about so ill just post pics and be detailed as i do the work.

If your interested how this just check on the thread every once in awhile.  It wont be a fast build im hoping to get it done in the next month or so but i know how that goes.

ill keep yall posted...

Im thinking it will look good and I cant wait to get it on there and post pics up for everyone to see.  I started grinding it down with a gator wheel and flap disk.  Hope to work on it an hr or so everyday till its done during the week.  I will keep this updated and post pics through the progression and snags!

Thanks for the input!

Alright I want to give an update....

I got the bumper on.  it is still not painted and it is not completely finished welding wise.  The tubes that cover the lights and are suppose to wrap around I cut those.  I am going to re weld the end so that extends just inside the dimensions of the front of the truck.  its hard to explain.  Also going to have to take it back down to fully prep and paint with bedliner.  over all im satisfied with the way it turned out.  took all weekend pretty much to get it on. the custom brackets were sorta a pain to do be cause it was picking up the bumper with the engine hoist look at it measure put it dow move it then do it all over again about 10 times or so.  the front turn signals are not on along with the cowl? maybe that what its called still got to figure those out.

anyways here are a couple of pics with it on the truck.  like i said still needs alot of work but its on there.....

I have to say that bumper looks mean as heck. It should put the fear of God into anyone thinking about pulling out in front of you. You can pull the look off since you have a 3/4 ton with 38's. If it were mine I would cut off the two small bottom pieces and run a tube around the headlights. Just a thought...Looking pretty good tho.

Yea man i was hoping you would check it out since you were interested! yea im not completely set on the headlight bars but im up for anything! Im pittle around and take everybodys considerations into finalizing it.  The first thing me and my buddy said after we stepped back and looked was we joked "Welp now ready for the zombie apocalypse" but im really glad how the lower part of the bumper turned out and looks, i was worried it would hang too low and stuff but we were really able to mount it wherever we wanted since we made custom brackets.  i wanted to go about 1 to 2 inches higher but we decided on that spot due to the headlights and the bars.  but in the end that might not even matter...oh well im ok with where it sits.

thanks for looking and anyone else who wants to leave feed back negative or positive im ok with that.  just keep in mind its still a work in progress any ideas would be appreciated to...

Well i know it has been a long time since I provided any updates mainly cause I have not had the time and money to throw at it.  However for anybody interested I do have a couple of updates....

First I thought I had a timing issue with the truck and I had posted in another thread asking for help and it has since been long gone but anyways I finally have figured out a issue I have been having since I first started up the motor in the truck.  I thought I was experiencing kick back on the starter and thought it was a timing issue.  This weekend I learned that I did not have the ground set up right for the truck.  Mainly cause to be honest I did not know any better.  I had a negative wire from the battery to the frame and then piggy backed sort of from a spot 6 inches away on the frame with a ground to the alternator bracket for motor ground.  I have since redone the wires so I have a ground straight from the battery to the frame as I did before However I now have a ground straight from the battery to the motor to provide a more continuous loop and BOY did it make a heck of a difference. The starter turns over faster than it ever has before! truck fires right up everytime. Very happy about that I was starting to worry that the starter was big enough for the 10:1 compression but its all fine and a cheap solution!

Now on to my next immediate purchase......I have a chance to buy some practically brand new 20x12 Fuel Octane rims with the deep lip from a really good friend of mine. My ground hawgs are in really sad shape and i am fearful that it was not going to pass inspection this time and I have been really worried driving it around for my own safety.  So I plan on buying the rims and start looking for a descent set of tires for the 20s.  I am actually honestly thinking about going with a 37" tire and taking off the 2" body lift.  For drivability, safety and ease of getting in.  I will hold on to the BL cause its not hard to put on or take off incase the future changes but I am getting tired of ripping pants getting into the thing lol.  I think it will still have a really good stance and i wont be losing ground clearance since the ground hawgs run small anyways and measure around 36"

I know some might hate the idea of custom larger wheels and are old school but I personally think it would look really good and I guess in the end my thoughts and opinions are what matters. I like my BMF 20s on my ford and would love to pick up a set for the gmc....

thats all for now
Title: Re: SMason's 78 GMC K25 4x4 Build Thread
Post by: Scott M on July 13, 2016, 02:24:56 pm
Sooo now I am going a totally different direction..... 180 degrees different....

I am going to look and plan on buying another set of ground hawgs and as long as they are not dry rotted past their life (which the guy says the cracks arent that bad at all) but they are 44/18.5/r16.5. I got him to measure the actual height unmounted and they measure right at 42"

So i have been reading more about fender trimming as well as "zero rate springs" the plate that bolts to the spring pack and gives an inch of lift in the front as well as moves the axle foward 1 to 1.5".  I have read that alot of people do this however it was the first I had heard about it.  So plan on getting the tires this weekend getting them mounted and then start marking and trimming the fenders.  I will have lots of pics after this weekend as long as the tire sale goes smooth.  Then I will order the zero rates after I get the fenders trimmed.  Mind you this truck is mostly a beach cruiser no rocks so I wont need full flex but I will need more than just street driving.  I am a little hesitant cause this seems to be a pretty big jump considering my current tires only measure to 36" but they do look rather small on the truck.  More to follow.... Its exciting times for the ole GMC

I like it, would you maybe be able to provide with more details? I love the color I want to go with a very similar color. 8)

I am wondering do you have much time between now and when you painted it and can say it has lasted? About how much money do you figured you spent? Looks like you put a clear? This is out of a rattle can right?

Sorry I have so many dang questions the truth is I am really close to doing this myself and I think you did a dang good job at least from the photo.  I just havent felt like sanding lol.  But I am getting more motivated all the time cause mine looks like crap and you sir might just be able to help motivated and push me in the right direction.

Any other valuable info regarding painting it? I dont have many resources to get it done. I sure do appreciate it!

well you will be a little disappointed  lol... i bought it in quart cans and i dont think they make the color i used, i had a hard time finding enough to paint my truck.
This is what i used but mine was hammered metal grey
https://www.amazon.com/Rust-Oleum-239073-Hammered-Finish-1-Quart/dp/B000KESBIO/ref=sr_1_1?s=hi&ie=UTF8&qid=1468632469&sr=1-1&keywords=rust+oleum+hammered+metal+quart (https://www.amazon.com/Rust-Oleum-239073-Hammered-Finish-1-Quart/dp/B000KESBIO/ref=sr_1_1?s=hi&ie=UTF8&qid=1468632469&sr=1-1&keywords=rust+oleum+hammered+metal+quart)

I spent somewhere around $75 including paint and thinner. i had to spray the truck with grey as a base coat to keep the different color panels from bleeding threw then i applied the hammered grey. its definitely not easy to spray unless you have a controlled environment... I just eye balled the thinner each time and also had moisture in the lines. That coupled with the thinner wanting to separate from the paint unless you constantly shook it cause me to have a some what hard time keeping the texture consistent. The hammered metal is a unique look and gives it a rough looking texture. The reason i chose the color i did is because i didnt like the plane colors... the hammered look breaks up the color and in my opinion helps it not look plain.

Here is the grey sprayed

Rear fender, as you can see the texture is tighter than it is on the cab ( next pic)

Thanks man I really appreciate and I love that look. To be honest I think that is exactly what I want to do now.  I have a cousin with a shop (private not in business or anything) and they have done some minor painting in there ima see if they would want to help me out.  I mentioned it to them this past weekend actually.  I appreciate all the input in your post.  I love the price tag as well.  Can you put a clear coat on that hammered type paint? and If so do you think it would have held up better.  I am a total newb to paint. I dont know about mixing or application and moisture and stuff but I know that my cousins do know more than me.  Thanks!

I did end up getting the 18.50/44 ground hawgs this past weekend and I mounted one to my wheel.  I am actually suprised I thought the fender would look a lot more stuffed but it doesnt.  I also picked up a brand new set of zero rates made by ORD from my cousin who bought them and decided he didnt need them.  So that was a great deal.  I will be putting them on this next weekend.  But I know that this tire measures to right over 42" and 15" wide.  I will have to cut the fender but that wont be a problem.... here is a few pics with it on the truck its front passanger.  The old tire measure a little above 35".  Pictures actually dont do the new tire justice it is a big difference!  Also on the side shots the wheel is turned in towards the fender

I have a few updates to share after this weekend.  This friday I went to check out a trailer as I no longer want to be driving this thing on the road anymore.  Plus I dont have a trailer and thought it would be a good investment.  I found one and went and bought it.  its a 2005 PJ Trailer 20' Overall Length (17' Flat Deck/3' Dovetail).  Has a GVWR of 14K lbs Its a pretty solid price. And I drove off with it as a steal couldnt pass it up.

(http://i1151.photobucket.com/albums/o626/scottmason_67/IMG_20160723_114819_zpseirkzjxw.jpg) (http://s1151.photobucket.com/user/scottmason_67/media/IMG_20160723_114819_zpseirkzjxw.jpg.html)

Then saturday I was able to take the tires off and run them down to a tire shop in town and have them mount the remaining 3 tires.  So I did that (boy was it hot). It took a couple hours no joke.  Idk about yalls lug nuts but mine have always been tight and with just a cross it takes a dang lot of energy just to pull a tire and put one back on.  They run tight all the way off and they had a little bit of antiseeze last time i had to do this.  So some pictures below are with the tires mounted.  The tires did rub the back fender just turning on flat pavement.  So i knew it was time to try and get the zero rates on. Pics below without zero rates...

Sunday afternoon I went to my cousins house and we were able to install the zero rate springs.  I ended up going with the hole to mount the axle an inch and a half (1.5") forward.  The use of a shop lift to be able to move the truck up and down was amazing.  We had a little trouble getting the pin to line back up but we finally coaxed it in there and massaged it in after alot of up and down clocking the axle back and forth. After the install I had to pull the front driveshaft. I am going to have to take it to the driveshaft shop and have them lengthen it.  It wasnt really close to working (I think It was a little on the short side to begin with).  But thats no biggie! I am extremely happy with the results from the zero rates.  It leveled out the front (I cant hardly stand forward rakes). and it did noticably move the axle forward and gave the tires alot more clearance.  I dont have any pics with the zero rates on flat ground but a couple playing on a little hill at my cousins.  While we were in there we also removed the sway bar from the truck.  I will need to still trim but it is alot better off with the zero rates!

dang nice truck man by brother in law has an 80 stepside that is on 44x18.5 super swampers. looks great but its lifted to heck and back to get the clearance, he didnt want to cut the fenders. Im not really wanting to go over 38s though myself. heres a pic of his truck. Now dont get me wrong, he has not got alot of room for flex, but his springs are stiff as all get out. Its a 4 speed and i hit a pot hole while downshifting and it threw me so bad that my foot came off the clutch and it stalled out. he was thinking about cutting the fenders because as you can see, theres some rust and such, but he was also thinking about getting some new ones (or good used ones) and cutting those before a paint job is in order.

Man I do like step sides. I think its because you dont see as many fixed up.  I also Like the wide tires to me makes the truck.  On the trimming think either way would work fine.  If he is rubbing in the front on the fender well towards the cab, i would really check out those zero rate type springs. all i can say is before my tires would hit the back of it towards the cab at about 1/2 turn or so and with the zero can turn all the way.  But thats flat on the ground not moving driving and it going up and down on bumps and turning at the same time is a different story for me thats why ima trim. 

Thanks for the response.

My buddy has a vinyl decal printer I think a phrase is in order lol.  I saw one on an old ford here in town that said "I PULL OUT" hahaha ;D

Nice truck! What gears are you running with the 44's? I hope you get around to painting it. It would look awesome in that hammered gray.

Thanks man, I just have the stock gears which i believe to be the 4:10 since its not military or anything.  When I went to 44s I gave up on driving it down the road...thats why i purchased that trailer I had it loaded up on.  In 4 low gearing doesnt seem to hurt it much.  At the moment unfortunatly i put it on the back burner again but I will def keep this thread going as I do more... thanks for looking!

So I picked up a rear pipe bumper for the truck that is actually made for an 73-87 truck. however the previous owner had welded the old bumper brackets straight to the frame so I am going to modify this bumper to mount to the outside of the frame instead of the inside where it should be.  I also picked up a welding machine.  This whole time I have always used buddys or brought stuff over to them to get it done. Pretty excited I wont have to rely on anybody anymore.  I am also going to fix up the front bumper a bit more and stiffen up the brackets me and a buddy welded up. Any suggestions on an easier way to take the paint and rust off the front bumper with minimal grinding and I dont have access to any blasting and dont really want to pay...I have been looking up different chemicals that are suppose to do the job...

forgot to mention I want to get rid of the rusted out rocker panels at the doors and want to weld in rectangular tubing in like rock guards or i think its called boat rights maybe? idk if thats right but thats my other plans.  now that i have this welder plan on getting back on this thing...

Okay so I got the brackets rewelded on and i also adjusted for the 2" body lift.  I used this stuff called aircraft remover to take the old powder coat off in hard to grind places like the diamond plate and stuff.  Then i decided to just paint it with a couple of heavy coats of black bedliner.  Im pretty happy with the way it turned out.  I just finished mounting it this past weekend.

making a little progress on the front bumper. By far not perfect or show quality but hopefully it will last a few years. i did learn my lesson after buying these to bumpers.  dont pay or even take for free a really rusty bumper.  i cant say that it has been worth the work.  Take and grind/brush as must rust as possible everywhere. chemical stripper to remove old powder coat (PITA) and then treat with ospho and then clean up and prep then prime.  next is bedliner then get it back on and hopefully be a tad straighter and stronger as i have worked on that as well.  Hopefully get it on this weekend and ill post a pic completed weather permitting.

Finally got the front bumper back on. Pretty happy with the way it turned out. Im going to put the project on hold for the most part till the end of April but i might sneak in a few things if i have time.  Studying for the PE exam on April 21st. I might pick up military 46s between now and then....

Picked up a set of 20"x10" KMC brand wheels. I figure they are an older style (10+) years old or so. They have some pitting but I got what I think is a good deal on them and im not looking for perfection just a deal. hopefully get the tires mounted to them next week....

Took a little longer than anticipated to get the tires mounted to the wheels and lots of stops at different tire shops until one did them for me.  I went to semi/ag places and one wouldnt touch them because the tires were older than 5 years old. another wouldnt touch them because they said the tire wont bead up on the truck rim cause its not made for it.  so finally after many other stops to auto tire shops found one that was willing to give it a shot.  the hardest part they had was getting the rim through the tire and they did it the old fashion way with lots of man power big crow bars and lots of jumping.  But got them on and tomorrow they are going to go on the truck to mock up were to cut the body. anyways here is a pic of one of them mounted and after this weekend I will have pics with them on the truck.

Got the tires on the truck this weekend.  I did a little bit of trimming in the areas that absolutly needed it just to get the tire on.  I plan on trimming more right now its driveable with the trimming Ive done so far however riding up and down the beach it might still rub a bit so im going to go ahead and trim the rest soon. but for now they are on.  also I am only trimming to the max of the inner fender in the front for now.  If I rub bad I will modify and massage the inner fenders to get more clearance.  I dont plan on doing any extreme flexing.

Looks like those rims are reverse cut from best I can tell from that pic.

If that's the case the tire goes on from the back side of the rim.

Is that what they did?

I think I know what you are asking.  I only watched them mount the first one but when they did that one they layed the rim on the ground and put the tire on top.  so I would say that answers your question as no....  I know they had a hard time, but it was 90 degrees and it was at the end of the day when they mounted them.

The fatter thicker portion of the rim on the outside perimeter between the beads with deeper dish style tend to be to the front making them reverse cut.

The thinner shorter portion is where the tire is mounted from.

Taking the tire off from the wrong side can cause damaged tire beads.


I know from experience.(https://uploads.tapatalk-cdn.com/20170605/340ac881ec27b0196bd1cc7daf78aca5.jpg)

Reverse cut ^^^^^^

Does this photo help in determining what I have? Also the beads of these tires were at least 1/2" thick.  Tires are pretty darn thick in general weigh about 220lbs without the wheel.  If I ever have to take the tires off the rim it will be because im disposing of the tire at hazardous waste day haha.  As long as they hold air can go up and down the beach and the truck isnt rusted out I intend on leaving them on there. They are 14 years old the tires so this will probably be their final mounting/dismounting at least I hope.

Thank you for the info

If it's facing up I would say yes reverse cut, wide portion is to the top because it is a deeper dish rim.

It's harder to install the tire from that side. The back side of the rim is easier to slide the tire on due to being narrow.

You will be surprised the # of places don't know.

I have old school slots and have to educate.

Yes its facing up.  Well thank you again for the info as I have learned as well today.  I thought they had the rim facing up and the tire over the top but I wasnt watching that closely and I have bad memory so I dont remember which way they had the rim.  I thought up but i could be wrong.  I will definatly remember this though if I ever have a set installed again and that I have alot of money into.

I have decided on a color for the truck.  Im going to go with the "Turquila" color.  Still a ways from painting the truck but have decided I want to drastically change the image of the truck and decided ima go that way.  Was going to go with desert tan or midnight blue.  I realize this decision hurts resale value but i dont intend to sell.  Anybody have any experience with tinted bedline coatings? Ive only used black.

Trimmed the front fenders some more.  I am going to have to do a little bit more trimming on the front fenders towards the cab as it rubs a tad when flexing some and turning.  I also need to figure out what im going to do to close the gap between the outer fender and inner fender.  any ideas, guess ima shape some sheet metal and attempt to weld to these thin aftermarket fenders.
