7.25 rear woes....

Go with the Ford 8"rear. Parts are plentiful, way stronger then the 7.25 and have the dropout center. Makes it easy if you ever want to change gears. Plus you have options on limited slip, locker or spool. I got mine out of a Maverick, but I think the early Mustangs (64.5-66 or 67-68) used the same rear so they are available.
