Are A body small bolt pattern 10 inch rear drums interchangeable between a 7.25 and an 8.75 rear. And yes, both rears are original A body rears.
Lots and lots of them did, some even with the large bolt pattern.I am unsure if any small bolt pattern 7.25 rears came with 10" brakes. Did they?
I believe the bearing hole is smaller on the 7 1/4 alsoAs for the OP’s question…..yes, the drums are the same. The backing plates however….7 1/4” has only 4 mounting stud holes whereas the 8 3/4” has 5. Yes, you can drill the 5th hole
Ok, that's what I was thinking that only the large bolt pattern came with 10" brakes, but I take your word for it. Thanks!Lots and lots of them did, some even with the large bolt pattern.

All the '66 and later V8 cars had 10" brakes regardless of which rear axle they had.I am unsure if any small bolt pattern 7.25 rears came with 10" brakes. Did they?
I edited my typoThere is no 4 1/4" bolt pattern on a Mopar that I'm aware of.
Do I need to take a photo of my stock SBP 10 inch rear drums on my 7 1/4" for you to believe!Ok, that's what I was thinking that only the large bolt pattern came with 10" brakes, but I take your word for it. Thanks
