Paniolo is correct. I will have a back up if the hubs dont work. Ill carry around a a set of splined axle flanges that can bolt in place of the hub if something goes wrong.  If anything, ill run the hubs in town only and if I go out ill slap the splined flanges on. I would love to have a nice expensive locker instead. But thats the thing. Expensive. Our family friend can machine tge double splined axle shafts and flanges for real cheap, I can buy a set of hubs for fairly cheap and my dad is buying the spools for me. Its the cheapest route for me. And if I go through hubs, I can just leave the splined flanges on, or even have an axle flange made with a bearing instead of splines so it free spins.

well why not just do a dual transfers stick and unlock one of your front spooled and leave the rear in neutral then just a a fwd trick with a locked rear. dont know if the wear on the rear will be less but it might due to the fact your not using them to push

A spool runs mid $100 range.  A lock-right can be found mid $300 and the Detroit mid $400.

Still think you will be time and money ahead to get a rear locker since it sounds like street use will be the primary task.  Even if you forego the front for now.  Get your parents to kick in whatever they were going to for both spools and chip in the difference for a lock-right.  Then save your pennies to get the front spool in a few months.

we been trying to tell him this. Also not sure but wouldn’t a loss of traction be a issue when you turn to the side that has power?

Look around for a used Detroit.

They show up on eBay from time to time for less than new.

I got a 35 spline PowerLok off of eBay for my Dana60 front for $199.00. Those normally go for $425.00+.

Quick update. Im picking up the truck within the next week. I found a cab on craigslist for 50 obo. Its a 79 cab with title, no doors, has windshield and rear window, rust free with unmolested wiring and ac. The K20 has brand new fenders on it, but I will be putting those on my c20. Im trying to find a c50 front clip for the k20. Im putting my after market doors on my c20 and my old c20 doors on the k20. Cant wait to get it!

I agree with what these guys are sayin, just save up for a detroit, even a used one. I was more or less keeping up with this thread, but it hurt my brain a couple times, and I think the whole hubed rear-end thing is gonna be more trouble than its worth.

Since you're gonna have a K20, I think its time to drop the C20.  ;D

Actually, im going to lower my c20 an inch or two just for a better stance, then put some fatty tires on the rear. Its gonna be my street beast and my k20 is going to be my offroad beast.

After I move again, which will be in a few weeks, I'm gonna finally get the 74 in order. I need to replace the steering box and pump, then drop it. When I can do without it for a few weeks, it'll get shortened. I have a buddy thats willing to weld it up for me.

I'm very excited about this. End this year on a high note!

Well, good news. My mom promised me 2800 dollars to me on my 18th birthday that I got from a lawsuit in 3rd grade because a kid broke my nose and didn't get punished, so we sued the school district because the teacher and staff of the school were mentally challenged when it cane to any sort of discipline or intervening. Well, she gave me 300 cash today, I picked up a rust free, dent free, clean cab with all wiring intact and ac intact with a clean title 53,000 original miles for 50 bucks. Ill have pictures of it tomorrow. Then, I can get my license reinstated any time after Monday the 26th. My mom is going to write a cashiers check for 2500 in the next few days. So sometime during next week or weekend my dads driving.me up to his uncles and I'm driving my big, yellow, soon-to-be beast, K20 home. I cant wait. List of things I'm going to do.....

Pull fenders off of both trucks
put K20's brand new fenders on C20
pull interior out of K20, and take cab off
Split the tcase and tranny so I can remove the shift rail to grind it for Twin Stick
put high hump tunnel in the new cab out of the old
put new cab on K20
put my aftermarket doors on the C20 with my C20s internals
put my C20s doors on the K20 with new cab and K20s internals
put my C20s old fenders on the K20 until i find a C50-60 front clip
primer both vehicles
paint C20 with chosen scheme and design
decide on k20 paint


Those are the first things I'm worried about. Ill deal with positraction later on down the road. Spool in front and ?? In rear.
