10" drum source?

Ditto. I bought some 10" rear drums from rockauto a few years ago. At least the description implied they were for the rear (a bit confusing). Turned out they were common front drums, but only $22 ea so I added them to my front drum stack. If after trimming off the snow lip, they don't rub on the backing plate, I can't imagine any problem. Perhaps the drum could crack 15 years from now, but that is true with any drum.
