Well i know like a 91-96 cherokee has an 8.25 with a 27 spline axle and the 96-01 i think has an 8.25 with 29 spline i think. All those modifications dont sound like it would be too hard. How are axles shortened? Oh no,stillwater people found me. The jig is up ha. Didnt think that would happen. Small world
