    Dashboard "frame" removal 1984 GMC C1500

    I’ve got a hacked one I plan to replace. I plan to cut from the defroster duct to speaker opening to the side and leave the forward piece in and butt weld

    Finally got a running 65 C10

    Yes we used to bore them .125 over in the early 80s and called them 301s not realizing that made a 4 inch bore and basically a 302 like the early Z28s

    OEM cylinder head castings - 1977 K10

    Remember that GM went to thinner (lighter) castings in 1977, so if you get 882 castings, there is a difference in early and late heads. The early heads had a straight edge under the spark plugs, where the later heads were “scalloped” around the plugs. Early heads Later heads The 010...

    Corp 14 bolt brake line difference question

    The bottom rear is from a 1 ton, as you can tell by the shock bracket placement. (In front of axle on passenger side on 3/4t, behind axle on pass side on 1t. Both srw and drw axles are this way) Maybe the difference in lines is 3/4t vs 1t? Or one with the load equalizer valve and one without?

    Nice looking old 65. Kind of partial to them, as still have the old 65 my grandfather bought new here in the little town I live in. Still got the 230 and 3 on the tree.

    Definitive interchangeable parts thread 73-87(91) (non-drivetrain)

    Those old 208s held up better than most folks think. From privates to NCOs, they were well tested for strength. Also had a better gear ratio which was needed with the NA 6.2s, even with the 4.56s gears in the old 5/4s

    Definitive interchangeable parts thread 73-87(91) (non-drivetrain)

    The M1008 CUCVs (we called them “Cuck Vs”) were listed as 1-1/4 ton, and had NP208 (chain driven) transfer cases. But the CUCVs were not the same as your normal assembly line vehicle. Most of the M1028s had NP205s, but some were sent new to unit with NP208s. Was a big change going from the old...

    Another leaf spring question: (plastic shims).

    Shop around by pn I used the pn D-58 from KC Spring (not sure d-58 is what you need, just used it as an example) https://www.generalspringkc.com/2-1-2-wide-square-leaf-spring-tip-insert-with-centered-oval-button/ And found them alot cheaper here...

    Early 4.3 upgrade?

    While not really relevant to the original post, Some of the later engine changes (post 98) included elimination of the egr valve and updated injector design in 02-03 and updated ignition in 07, that used a 58x reluctor wheel instead of the 3x that had been used since ‘96. Also, around 99-2000...

    SM465 locking between gears

    Pull the shift lever and check for slop in the pins. (Circled below) slop in them will cause shifting problems.
