seems like 90 was the year that some stuff may work in newer XJ's or they may not, a transition year. so what was the spline count on the transfer case input shaft? i have read on here both 23 and 21. i want to know from someone that has first hand knowledge with a 90 xj. my 242 is shot and is my DD so im just looking to replace the case and not rebuild the 242
