If both cars are 1986 or newer, it SHOULD bolt in I have heard that there is a lot of work making a later diff work on an earlier car and Vice versa. As for the rebuild, I have no idea, best thing is to look it up in the FSM and see. You would need a press at least to seat the new bearings or you could smack them with a mallet and pipe

You should also get the speedometer as the gears are different.
Good luck!
