All,

I need to know where to drill a 9x13 1967 Ludwig tom for a large, round knob muffler that has the smaller screw below the knob. I know it's supposed to be opposite the badge. Specifically, I need to know the the hole spacing from the top of the bearing edge to the center of the knob hole and how far the center of the knob hole is from the lugs.

(And don't freak out: the tom was drilled for a diamond mount at one point and then nicely patched up. Since the shell has already been molested, I have no issues about drilling for the muffler, which I will actually use.)

Thanks,

Buzz
