The only thing I can think of that is different is the gauge surround. The pre 95 have a different cut-out for the steering column than the 95/96. The front seat mounts are different but I can't remember the year that they changed. You will have to watch out for things like whether or not you donor has the same options as your rig has, over-head console, pdl/pw, rear cargo cover, etc.
I have swapped out interiors in 3 different XJ's and i can't think of any thing else.
