Im probably going to go the junkyard route. I actually found a 92 caprice same as mine there with only 80k miles on it, it was really clean. Unfortunately it had the same rear end as mine. I did get lucky and took all the insides.

seats/dash etc.
I hear its not very complicated to install the axle, and its basically four bolts. Is this correct? Could I get away with doing this myself? Im going to have to pull the part off twice in essence, once from the junkyard and once from off of my car. I'd like to think im pretty mechanically inclined

and after removing the part twice I think I could install it once.
