get a dana 20 t-case and use any rear end you want. or re tube and get axles made for any axle you want. as far as something offset that you can just bolt in, i can't think of many. maybe something out of a quadra trac fsj. i think they came with offset amc 20's, maybe even some 44's. the full size amc 20 is not the same as the cj turd everybody complains about. it's a little better.
