What spline transfer case do I have?

I've got a '96 XJ with a 231 transfer case, and an 8.25 rear end. I am planning to install a 242 t case this summer, so I want to start looking for a good one. What years will fit my '96? How do I know if I have a 27 spline or a 29?

I bet you have neither. 27 or 29 spline referes to the rear axle. You have 27 back there. You have a 23 spline t-case.


Whoops, don't I feel stupid now. Thanks for the correction.
 
What I'm curious about is does it require a different driveshaft, does the 242 stick back further than the 231....
