Jeep Cherokee 8 1/4 to an A body ?

The Ford 8.8 is slightly narrower than the D35, measuring 59.75" WMS-WMS vs 61.25" for the D35-eqipped XJ (WMS is wheel-mounting surface). This means each side is going to be 3/4" narrower. While the narrower rear can mean tighter turns on trails, it also means the tires may make contact with the inner fenderwells unless you use spacers or rims with less backspacing

Don,
When you measure the 8.8 rear are you including the rotors? If so that only makes it .50" wider than a B-body rear (59.20"). I have put a B-body rear in a 71 duster, and I doubt the extra .25" would make any difference with stock wheels and tires. Will the 8.8 rear work with stock mopar rallyes, will they clear the rear calipers and is the center hole in the rim the right size? Sounds like an interesting--and cheap swap.
