FAQ or site to school me on types of axles, transfer cases, trannys for 4x4s?

[1970GMC468]

Hey bro! I live in Orland and I can maybe steer you in the right direction. I you search the 4x4 forums I turned my 1970 GMC big block 2500 into a four wheeler from a two wheeler. It is really not that hard. DIY4X makes spring mounts that make the front a breeze. Of course my Jimmy had rear leaf springs so that made the rear easy. I know just the roads you talk of, we have a cabin in Butte Meadows. Well good luck and maybe I can lend a hand.
