What other rear ends will work with my Dart?

I'm interested. After a long wait on a 8.25 he changed his mind. Rebuilding a 65 Dart GT 273 Go-Go Package. The 7.25 is trashed and no luck for a 8.25 or 8.75. I wanted the 5 on 4.5" LBP. I got it in 2011 when the P.O used the good parts to restore a Charger GT and put 66 doors and trunk lid on it. I'm at the point of putting anything in it or parting it out to get my money back.
