Oh, I get it. You want to know how big the drums are? I guess I should get reading brains. Or is it understanding gl***es. Old. Befuddled... I got a couple '52 drums out back I can check, but it's dark now. Tomorrow.
I'm thinking the standard shoes are 10" x 2.25" but the book doesn't give size, only application. Rock Auto shows 10"x2.25" too.
