Small Bolt Drums

I tried Rock Auto to no avail, searched the forum a bit, and decided to just post. Where can I find 10" drums with what seems to be 2 1/4 - 2 3/4 breaking surface, 8 3/4 rear, small bolt pattern for 1968 Barracuda?

I bought a new pair, but one is badly warped. I cannot return and the guy doesn't have others to replace.

Thanks
