I recently got my grandpa's 89 1500 Silverado when he passed away in October. Nothing wrong with the truck except it is 4x2 and where I live, I NEED 4x4 to get out in the winter as well as for hunting as where I hunt, the trail is only usable by tractor, ATV or 4x4. Now, with the number of donor trucks on the market, it shouldn't cost THAT much to do, and I can do most if not all of the work at my school's more than fully equipped auto shop. What I would like to know is which parts I would need and be specific please. (I know I will need both axles from the donor as well as the transfer case, and drive shafts) What years are compatible with my truck? What all needs to be done to do the conversion what all can just be swapped out, and what will I need to fab/buy? Any help is appreciated. This truck was his baby and in my opinion worth every minute I will put into the swap.
