How close are the aftermarket doors?
I recently purchased a set of the AMD doors for my '76. We'll be fitting them soon. Out of the box, they appear to be very high quality. I'll report back on how they actually fit the cab.- legend57

Haynes manual suggest silicone dielectric grease for ignition module?
I've experienced the same failures in the past. Always used the thermal paste, but still had failures with store brand modules. I stick with AC Delco because they tend to last longer. I still keep a spare in the glove box. I found this interesting article...- legend57

Keeping it in the family. My grandfather bought this 78 GMC brand new. After his death it sat for 18 years. I finally got ahold of it 2yrs ago, and ha

Inspiration indeed! Thanks for the pic. That is really close to what it'll be like. The light green along the middle will be white, but otherwise, that's it!- legend57

I think you were referring to the 700R4(?). Yea, I know they are definitely on the delicate side. My personal experience with a 700R4 behind a 400SB has been pretty good for about 20 years in my '57 Chevy. I know its a different beast, but I sure love that overdrive. I'll just have to always...- legend57

Next steps (roughly): 1 - Rust repair: Before I assemble much more on the chassis, I want to get the rust repair work done on the cab and have the firewall painted. I'm hoping to have the truck picked up within the next month to get that done. 2 - Drivetrain install: Once it comes back...- legend57

The transmission/t-case: Of course, the original set up was the TH350 with the NP203. I'm looking to make this a good driver and don't plan to tow anything heavy or any heavy off-roading, so I really wanted to get the RPMs down on the freeway. I choose to go with a TH700-R4 transmission from...- legend57

The engine: Ok, so I already mentioned I found an original 400. Since I'm in California, I need to build it and meet the heavy duty emissions requirements. So, I need to keep the smog pump, air tubes, and PCV valve. No cats and no EGR were on the heavy duty emissions for 1976 K20...- legend57

And the rearend going in... Note the 12 Ton jack stands. These are from Harbor Freight, too. They had enough height to reach the frame rail just in front of the leaf spring perch. I think ~29". They're huge jack stands.- legend57

After we completely cleaned the truck from sandblasting, I used Eastwood Rust Encapsulant on the frame and sheetmetal (underneath) (3 coats). I used their epoxy primer on the firewall to prevent rusting while I wait to get the rust holes repaired. I then used Eastwoods Chassis Black on the...- legend57

Restoration Tip #2: I'm now a big believer in getting the frame sandblasted and body media blasted. Even though the clean up is a lot of work, the result is much better than scrapping alone. Also, it's not that expensive. For $1K, I got the whole think done, along with about 20 other misc...- legend57

Here is one of the many fun discoveries I found. As many know, our trucks become Frankensteins over the years as parts are swapped out between trucks. I found out that the rearend was out of a C30 (shown on jack stands). Most looked OK, but the rear leaf springs didn't sit right. They were...- legend57

Back from the blaster. It turned out great. a few more holes on the firewall than I'd like, but the rockers were in excellent condition. Only a slight amount of corrosion on the cab corners to repair. Passenger side floor board needs some work, too. Overall, a good foundation. The only...- legend57

OK. Now we're waste deep in. Front end was all removed, interior was stripped, and everything underneath was removed. While I contemplated cleaning it myself, I quickly realized that was never going to happen. So, I prepared to take it to a blaster. While the best way is to remove the cab...- legend57

OK, now we're digging in. While the truck VIN called for a 400, someone had swapped in a 350 at some point. So, it's gotta go. Good motor and found someone who could use it. I did find a correct 1976 400 from a K20 locally. It was just about a miracle find. Never rebuilt, great condition.- legend57

OK, these pics are after I removed a lot of the visual ugly. This helped with the morale and my eagerness to start the project. Restoration tip #1: Morale is key to staying on a project. Do the little things that keep you excited about the project, even if it seems out of order or...- legend57

Hey all, Finally getting around to posting some pictures. First batch are as the truck was received back in Jan '22. Notice the faux roll bar. It wasn't even real tubing, just sections. Not bad overall from 30-40ft away. Yes, it would start and drive, but the cab would rock on the rotten...- legend57

Greetings all, Good to be here. Earlier this year, I purchased a 1976 K20 after a long search for one with a VIN combination I was looking for, and one that was a good candidate for restoration. Man, it was sure an ugly turd when it arrived, but I've spent the last 6 months getting rid of all...- legend57
