Drum for a nine inch Ford rear axle or a drum that is nine inches in diameter? I'm an old brake and front end guy and if you tell me you are looking for a nine inch drum my brain says that is pretty little and fits a small car.

On the other hand an 11 inch ID drum with a swept surface that is wide enough for maybe 2-1/2 inch brake shoes shouldn't be that hard to figure out. What bolt pattern?

 

I think he meant for a 9 inch rear end
