So I bought a used truck last week from a kid in town, and I think he did one two many burnouts with it, so know I'm trying to decide if it is worth rebuilding the whole rear end ( bearings, sun gears ) or if I should just swap it out with another rear end. I found a few on the internet back home one is a 14 bolt- 6 bolt hub out of 91 half ton and the other one is out of a 97 tahoe that has that gov lock locker in it. I'm not familiar with the gov lock, and I wonder how much work it will be to put that 14 bolt in, if I'm going to have to shorten my drive shaft or put a different yoke on it so the ujoint will fit. Any thoughts would be appreciated. Thanks.
