95 xj 4.0/ax15/new 242/d30 8.25 3'' boost. I picked up a 242 from a 96 zj a few months back and finally got it installed. The 231 I replaced may not have been original to the jeep. I was under the impression that the 231 would have a long input but it appeared shorter than the one on the 242 so I just left it. No reason to crack open the cases for the wrong input. Since the xj is lifted a little I didn't mess with the driveshaft shortening. The 242 had the external slip which made it 1.5'' longer than the 231. Any way the shift sensors are different so I need to find a pigtail from a zj and splice it in to the 2 wire on the xj or maybe there is a sensor that fits the 242 that will plug right in to the t case and and 2 wire. If the driveshaft becomes a problem I think I could find a shorter yoke. I seem to remember some were about 3/4'' shorter. If you guys see any problems that may pop up let me know. thanks in advance for your help, Joe
