i have a 93 xj 2 door sport. i have a 3inch aluminum spacer between the axle and leaf and it is flat as a board. i have an extra set of stock leafs from another xj and they were flat when they were on. i was wondering if anybody new a way to combine or mix and match these sets to help my problem. possibly help eliminate the 3inch alum spacer i have on it. any suggestions?
