Prefer the original one from a 87-90 model xj but id take one as long as the perch and shock mounts as well as the bolt pattern and pinion are configured for the xj. Any condition as long as it's not major....I can deal with the bearings gears brakes and whatnot but don't want pieces to weld together. A lockers a plus but not needed . Lemme know what you might have and your price needs to be PM'ed to me please. Thanks
