My buddy's 97 TJ with a 4 liter and five speed, screwed up his rear differential. He's had it in the shop for around a month since he wants to find a used rear end or diff.. He doesnt want to spend the big bucks on a new one since it seems to be hard to find one off of a TJ around here. Do any of you know of a good replacement rear that would fit a TJ without any major mods? Or if at all possible, do you know of anyone who might have one that is off of a stock TJ? He is past his warranty period also.
