Hello, I am new to forum and I have owned a 1981 GMC for sevveral years.Been close to selling  a few times but since the body and frame are still quite good (engine compression is 110 unofficially) , it still runs...I think I would like to start restoring it because I love the body and how it handles all my flower farm materials/lumber etc. I am not a mechanic but have a few who are willing to work on it here and there. I am looking for info on
1) what tire/rim options are for this truck it has 8 lugs and 16.5 at the moment hard to find 16.5 tires so far
2)muffler options
3) maybe how long it will run at 110 compression?

Any tips, advice or info on this model would be great!

I got new door glass felt rubber for the sill and the top frame of the doors for my 83. So there is a plastic xmas tree pin that goes in toward the upper rear of the door and a spade shaped metal tang that goes towards the front corner top near the vent window. My issue is i see nowhere to put this metal spade in the door frame. All of the videos from and Brothers show these guys just popping this in without a thought and no visual of anything. Anybody have a picture of what this is supposed to clip into?

My 81 K10  has two screws for the Fuel Filler Door and two for the fuel filler. Does anyone know what size the torque screws are for the filler doors and what size screw was supposed to be used for the filler where it mounts just inside the door? I have body manuals and maintenance manuals but could not find the info.

I’ve done some searching and the link in the parts section to identify a tailgate is dead but my question is…

What’s the noticeable differences other than shape of fuel door on the bed sides? I see there’s 73-76 and 76-87 options on various sites.

Same for the tailgate. There’s 3 different available aside from being plain or having letters on them (73-76, 76-80, and 81-87). Is it just their mounting hardware needs to all match up?

I have a 74 gmc fleetside longbed and currently have no bed at all. Just wondering if there’s any reason to get one year over another. Wanted to run a newer style latch kit that seems to only be offered on the 76 and newer gates.

Running a Boyd tank so no fuel door necessary to match what it “should look like” for a 74. Just want to see if I’m missing something before ordering everything.

87 Chevy V20 w/ TBI 350. Truck sat for a few months went to start ran for a minute than died. Air cleaner was 100% packed with a mouse house. Clean out and would start for a few minutes then stalled. I installed a fuel pump relay and can hear both pumps in the tanks prime. Same results. Installed an ignition coil and control module. Same result. I had all the parts so I didn’t have to buy anything. This morning (cold) started like normal and is currently running. I’m waiting to see if anything happens when hot. A few years ago I had the same issue and it was the distributor so that was replaced. Any ideas on what’s going on and yes there is gas in both tanks. Thanks!
