Ford Ranger rear end fit '71 Dart?

My father-in-law bought a restomoded 64 Rambler that someone put a 92 Ranger 8.8 in and it measures almost identical to my 68 A-body rear. If I'm not mistaken all you'll need to do is cut the ranger mounts off and weld on Mopar spring perches. Come to think of it, it has a 4 on 4.5 bolt pattern so you may need different wheels if yours are 4 on 4
