the ring and pinion is the same for 96 -2001.actually only some 01s.they switched ring gear bolts from 3/8 to 7/16,so if you wanted to use the gears only it wouldnt fit.obviously the entire axle is different so thats out of the question.i dont know if the differential cases are the same size or not,i know the carrier bearings are the same but som of the 02s have vari lock so that case is different.i dont know if that fits your housing.and just so we are all clear on the terminology,the differential case is the part that holds the spider gears and has the ring gear bolted to it. the carrier is the center part of the housing.anyways if you can manage to get some of these junkyard parts to work,yo still have to set up the ring and pinion so by the time you are done it probably would be easier just to buy a new gear set and be done with it.
