Possible to swap in a dakota/cherokee 8.25 sure grip

someone tell me, why NOT an 8 1/4 chrysler rear end out of the MILLIONS of 87-2000 XJ jeep cherokees that were built? spring pad perches -no biggie. any one know if the yoke would be the same for a 904 transmission driveline? the width may be a little narrow but has any one measured one of these? there are so many cheap gearsets and ratios available for these, what about a dana 30 or 35 out of the same cherokees? i recently sold my XJ cherokee to buy my duster so i didnt have a chance to compare,has any body out there checked into this?as im sure most everyone knows these all had a 4 1/2 in pattern and the newer versions have disc brakes to boot
