Jeep 8.25 Rear End ??????

ok so i came across an 29 spline, 8.25 rear end, with disc brakes, and 3.55 gears off of a jeep cherokee for sale. anyone have any idea if this would fit on an abody?

would have to be 51" wide from wheel mounting surface to wheel mounting surface right?

anything other thoughts? thanks

I wasn't aware that rear disc were available on Cherokee - know they had them on the Liberty (my 07 has them). Wonder how hard it would be to use the rear disc set-up off a Liberty and/or Cherokee on an A Body 8 & 1/4 or 8 & 3/4.
