I have a 94 XJ with a 4.5' lift. I just installed an SYE kit with a Tom Woods shaft. I need to change the angle of the rear dif. to line up with the new shaft. What is the procedure for measuring the rear dif. angle in order to get the correct degree shims. Thanks

 

when you go to buy the shims... rustys or something... they will say for what size lift... or use whatever that points it at the tranny...
