73-76 A-body 8 3/4 rear for 65 Dart?

When I parted out a 69 A108 van, I saved the 8 & 3/4 rear. I suppose it could be used as a donor for a cut-to-size rear end. Problem is the perches are on the top (not a big deal to removed) and it has separate shock mounts (also not a big deal to remove). Guess the best thing about it is that it has a set of 3.91s in it (unfortunately not a sure grip)
