My father in law has a late 80's/early 90's 3/4 ton extended cab long wheelbase pickup that he said I could have. Yes, its one of those trucks that looks like its a mile long and its 2wd, but its free. It doesnt' have an engine but I have a TBI350 that I could stroke out to a 383 and go with that. So, I've got the truck and the engine, but I'd like to make it a tow vehicle to pull my camper with. I'll have wife and daughters on board so I want to make it nice. I tow with my K5 now but one day I'd like to upgrade to a 5th wheel. My questions: 1) It seems that many of the restoration catalogs/companies stop at '87. I know engine parts are no problem but how difficult is it to find interior parts like panels, carpet, etc. for this truck. 2) Being a 3/4 ton would this truck have come standard with the 4L80E? Trailer towing package? 3) How can I find out which gears it has in it?
