Rear drum question 7.25 vs 8.75

I am unsure if any small bolt pattern 7.25 rears came with 10" brakes. Did they?
Lots and lots of them did, some even with the large bolt pattern.

As 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.
