If both are small bolt pattern, most parts should interchange. Some 7 1/4 rears had bearing adjusters for the carrier bearing, where some had shims. Depends on year, and after all this time there is way to tell if the rear is original to the vehicle.
There is a difference in the end of the housing, backing plates, axles, axle bearings and seals, between the large bolt pattern and small bolt pattern 7 1/4's. They are not interchangeable.

Yes. those were the problem. Everything out of 63 worked in 73 7.25.even pinion seal.Just finished bolting everything back together may have to wait on axle seals for the 73 .The ones I got for the 63 are differant .Hopping to up grade to a 8.75 ASAP .This is a quick fix with what was laying around. Thanks .
