    Vapor Barrier behind new door panels?

    Hi all. I have a 1981 C10 Silverado. Ordered new reproduction door panels that should be arriving early next year. When I messed with door panels in the past there was always a plastic vapor barrier between the panel and the door. There currently is no sign of one on this truck, and the door...

    Question about center grilles - 81-87

    I have a 1981 C10 Silverado with dual headlights and one of those 1980’s JC Whitney-style billet center grilles that I’d dearly love to replace with anything more stock looking. I found a decent stock C10 center grille about an hour away from me off of a 1987 truck (photo below). Will it fit...

    Blower Issue

    Just wanted to get this out there in case anybody else comes across this problem. Originally the blower on my 1981 C10 Silverado would only work on the first three speeds and never on high. I heard that this often is because of the high speed blower cutout relay being bad. Without starting the...

    Same horns all years?

    Hi all - I’m going through Facebook marketplace ads trying to find a replacement high note horn. Does anybody know if they used the same horns for all years, 1973-1987? I know not all trim levels had dual horns, but it would save me time if it turned out that they used the same Delco Remy horns...

    High horn not working on a 1981 C10 Silverado

    Hi all - the high horn (A note) on the passenger side does not work. The wire that feeds it is passing power, but no buzz, no click - nothing. I pulled the unit and tried hooking it up directly to the battery with no result. Did a continuity test and found that there was no continuity. Did the...

    Crate Engine Identification

    Hi all - I have a 1981 C10 that I bought a couple of years ago and have been slowly working on ever since. I know it originally had a 305 SBC engine and believe that it now likely has a 350 SBC crate motor. The previous owner said he thought the motor was installed about 20K miles ago by a...

    Recognize this?

    I found this inside the driver’s door when I was replacing the window seals on my 1981 C10 Silverado (crank windows, manual locks). There is no rust at all in the door itself and I can see that the doors have older aftermarket interior panels on them so I am not the first person in there. I...

    New to this: Rear end alignment?

    I got new tires on my recently acquired 1981 C10 that I know nothing about today and my next step is to take it to a local shop to get the alignment checked and a coolant system flush and fill. So is there such thing as a rear-end alignment? I remember hearing that this is a thing but don’t...

    Beginner Alternator Question

    I bought a 1981 C10 not too long ago with no real history on it other than it had a crate 350 motor put into it at some point, supposedly 20K miles ago. There's a sticker on the battery that says "5/22", so I'm assuming that's the date of manufacture. The battery died once recently and I...

    Door Hinge Spring Replacement

    While replacing the window channel seals over the weekend on my '81 C10, I finally noticed that the driver's door was swinging freely without resistance and I had to prop a garbage can in there to keep the door in place while working on it. Have always taken for granted that car doors will come...

    Painting rally wheel rim

    The spare rally rim on my new project truck had a lot of surface rust and a junk tire on it. I pulled off and discarded the old tire and sandblasted the rim. You can see where the rust came off but it looks pretty good and with the trim ring on it when in use, it is going to look just fine. I...

    Recommendation for Steering Columns Galore

    One more recommendation from a recent experience: this one for Steering Columns Galore in upstate New York. I wanted to repair the floppy tilt steering column in my 1981 C10 but was not ready to do that kind of work myself. The mechanics at the shop I used warned me that once you get into...

    Strong recommendation for Rob (SirRobyn0) at Luke's Redmond Automotive in Redmond, WA

    Wasn't sure where to put this - hope this is a good place. I just wanted to strongly recommend Rob Norenberg (@SirRobyn0) at Luke's Redmond Automotive in Redmond, Washington. I took on my first square body project only recently and needed a lot of help. Fortunately, other people on this forum...

    Spray vs Plastic Bedliner

    I have a 1981 long bed fleetside C10. The prior owner had an OK paint job done on the exterior but seems to have applied some sort of bed liner material himself and because of poor material and/or workmanship it didn't last hardly at all. So there's original paint showing through in many places...

    Busted Alternator Bolt

    Hi all. Sorry about the length of the post but I didn't take any time to take photos while this was happening. I have a 1981 C10 with what i think is a Goodwrench crate 350 motor of unknown age and origin. I'm not an experienced or knowledgeable mechanic. I bought the truck in December. I...

    Chevy C10 "Build"

    I realize that this forum is for other vehicles but what I came across doesn't seem to fit elsewhere... So I'm new to Square Body trucks and just bought an '81 C10 a few weeks ago. It has a lot of common issues and I've had a lot of luck going out on YouTube and watching people's videos on how...

    Greetings from Seattle

    Hi All. I've restored several air-cooled Volkswagens and have owned a couple of 1975 Kawasaki H1-F Triples over the years but have been out of it all for well over a decade. I started to look for a GM square body truck a couple of months ago as I thought having a long bed would be useful as I...
