So I have a mid 60's Slingerland COB snare, and I am missing a piece off of the drum (sadly was bought this way). I need to get the clamping bar for a zoomatic butt plate. The main part is there (attached on the shell) but the little bar that screws into, and clamps the snare wires to it, is missing. Sadly, the drum just doesn't operate as well as it could without it.

Does anyone know where I might could find this part? or does anyone have one they are getting rid of? I don't mind buying the whole zoomatic butt plate set, keeping a spare on hand would be helpful I am sure :)

Thanks so much for your help!
