    question about gmc vs chevy

    Not exactly. Front end sheet metal (fenders, hood, rad support) was trimmed out upstairs and conveyed to the final line in sequence from the far recesses of the plant. As a result it was imperative that the operator pay attention to the build sheet and put the emblems on that were called for...

    question about gmc vs chevy

    Now that I think about it: we had a "race truck" at the Proving Ground that was a GMC. Back before you could run anything at a Super Chevy event we used to change the grill and tailgate to Chevy in order to run the races. We left the fender emblems and dash emblems as GMC and nobody ever...

    We built some that were Chevy on one side and GMC on the other. K

    1981-82 Metal Lower Tailgate Mldg

    I did not remember them being any different than the later years (fully adhesive w/o clips). The elimination of clips and holes was a corrosion prevention measure. K

    Decal locations

    I don't remember seeing those on a Blazer. Especially the orange one. K

    Rear disc conversion

    Additionally - the rear brakes are "throttled" by the restriction in the proportioning valve by some percent (like 40%). Why not bump the pressure up and let the existing rears do a little more work? It's like having a carburetor sitting on a restrictor plate and then deciding you need a...

    Can you swap a stepside box out for a fleet?

    Yep. Same attachments. K

    Emblem help needed?

    I like them better without the fender emblems anyway. K

    Emblem help needed?

    No. Trim level is not encoded in the VIN. GM Heritage Center archives to not go back prior to '76/'77. If the truck was built in Canada, or built in the US for Canadian consumption, then GM of Canada would have the build info: https://www.vintagevehicleservices.com/ Otherwise your only hope...

    3 on the tree

    I can't judge you for wanting a three on the tree, or help with your selection of trans. I will add this, though: back in the early 60's, before four speed shifters were robust and plentiful, the racers would go with a steep steep rear gear with a three on the tree. That would allow them to...

    Panel Gaps/ Body alignment

    Good video. A few observations and comments: a) Door fit – in the assembly plant the doors were fit in the cab shop and not removed again after that. In other words, raw sheetmetal prior to ELPO dip and paint. https://www.73-87.com/7387info/Assembly%20Line.htm b) I also agree that the body...

    New to pickups & fifth wheels

    I would add: I have two standard lead acid batteries in my little camp trailer. I can go a week in the boondocks and it barely moves the needle off full charge. (Admittedly that's just running some reading lights in the evening, and the water pump). I am solar capable but at this point I...

    New to pickups & fifth wheels

    Trailering chart: Keep in mind the values across the top are GCW (Gross Combined weight, not just the weight of the trailer) so they include the weight of the truck. K

    Terrible gap

    Here's how we did it: "Quote=Keith Seymore What we used to do for fender shims is tape a packet together, like 3 shims, and we would run those all day whether the truck we were currently building needed it or not. Eventually the final repair supervisor would call back and say something...

    There should be shims here, here and here. K

    Door gap

    This is correct. Additionally, the stripes had a clear mask over the top of them. They were applied directly to the primer and formed the top border of the two tone. K

    Side tracking

    2wd or 4wd? The 4wd front axle is wider than the rear. K
