    What ever you decide to do, Make sure that the gear ratio in the rear matches the ratio in the front! If you dont then you'll be replacing them both anyway! I assume that the engine in that jimmy is a 5.7 deisel. And i'm almost certain that the gears are not 2.73 they are probably 3.73 That is a good driving gear even for 38's. Unless you are building it to go off road alot. If you drive this jimmy on a daily basis I would'nt change them.

    Junk yards and Craigslist are continually the 1st places i glance. i do no longer comprehend the place you're yet Olympic 4X4 in Snohomish Washington is a huge place interior the Seattle section. As for what has those axles i could look for older a million/2 and 3/4 pickups, like the 70's fords.
