Anyone look at an XJ cherokee rear end for a BBP conversion?

Hey guys,

I'm looking at options for my duster when I do a front disc brake conversion to get the BBP in the rear. I'm reading through the ford 8.8 thread, but I also had an epiphany late last night. I looked it up, and an XJ cherokee has the 5x4.5 bolt pattern, a centered pumpkin, and a 59.5" drum to drum width, so about 2" wider than an A body rear, but an inch narrower than a 68-70 B rear. they came with dana 35's or corporate 8.25's. looks like manuals came with 3.07 gears, autos with 3.55's and tow package with 3.73's.....

looks like all you would need would be a 7260/1310 conversion U joint and getting the driveshaft shortened to the right length....

has anyone done this swap, and can you think of a good reason not to use an XJ 8.25 in a slant 6 or mild V8 duster?

Thanks,
Patrick
