Bolt on replacement for 7.25 65 dart?

A viable option for a rplacement rear is a 8 inch Ford, from a mid '70's Comet, etc. almost a bolt in. Need one from a V-8, that has the 5x4.5 pattern. Need to do some looking, but Ford guys swap them for a 9 inch, so reasonble price, and lots of parts available.
PS: I used 7 1/4 rears for many years with good results Running low 13's with slicks. But can't get parts any more.
