I have a 95 XJ with a 23 spline t-case, im getting another one to swap in from a 91 since mine is completely shot. Some of the 91's had 21 and most had 23, i need to know how to figure this out in order to know if this T-case will work. all info would be appreciated.

 

Basicly you'll have to count the splines.. That's the only way I know to know for sure..
