Howdy y'all. Been playing with these things since i was a kid. Currently have 4, a 46, roller 302&C4, a 68 shortbed, not sure yet, but thinking a 429 &4R100, a 69, injected 302 & C4, and the latest acquisition, a 77 supercab, soon to have an injected 5.8 & 4R70w. Tech support for an automotive performance company by day, small wiring /repair shop by night. Stumbled across this place looking for an exploded view of a 77 tailgate. here we go....
