I used a ZJ front driveshaft for my rear. It wasn't a full-time 4 wheel drive rig, it had the 231 t-case. I had to have it lengthened for my application, but then again, mine's got around 7" of lift and an 8.8" rear. It was only $15 for the shaft at the junkyard, and another $90 to get it lengthened & balanced.
