I knew the XJ had a 21-spline shaft from the transmission to the
transfer case and I had a 23-spline on my YJ. I decided to use the transfer case
off the XJ. There was nothing wrong with the one I had but I really didn't want
to go swapping shafts and splines if I didn't have to.
I removed the transfer case from the transmission and it was
pretty obvious how far I could clock it.
