I just bought one myself this weekend. The columns are different lengths.XJ is short buy about 3 inches. The sole plates are different but I do not believe that to be much of a problem. I was going to remove it since the sole plate on CJ and YJ are removable. I bought mine to swap the wiper switches from the XJ to a YJ column I have without intermitt wippers. The parts are interchangeable. I did have to customize the switch some. The arm that works the dimmer switch is different. A little trim as you go and it works fine. I hope to install next weekend. The u joint ant the end of the column is also different. You will need to buy a YJ intermediate shaft or get replacement ones from Flamming River. I did this since I have their shaft. YJ and XJ's use a DD shaft end and the CJ's use a splined end. Use what ever you have avalible. Good luck.
