Ok, this is going to be a little off the beaten path, but does anyone know the diameter of the ball on the end of the post of Slingerland's set-o-matic tom mounts? Doesn't matter single, double, or super set-o-matic....the ball size should be standard amongst all types.....need to know to make a frankenstein mount to make a 90'ss HHS mount work with a set-o-matic tom bracket.......
Anyone?
