The must be a good drum shop in the Atlanta area where they most likely have a parts bin with many pieces from rail conolette. I'd be amazed if they didn't have the piece with the nib or tooth or whatever we want to call the the little metal bump to fit into the desired hole in the corresponding piece. If there is not a shop near you, phone Rockin' Robin in Houston. Ask for George or Bart. I have done a ton of business with thes folk. They are terrific to work with.http://rockinrobinguitars.com/
Thanks for another helpful reply.
Sadly, most such places in ATL were swallowed up by Guitar Centers. There's a new place in East Atlanta that I could try. Atlanta Pro Percussion is one of the lone holdouts, but they focus on high-end MIJ stuff, and although they know a lot about vintage drums, they don't really keep stuff like that around. I get most of my bits and pieces from Philly Drums or Olympic Drums in Portland, but as of yet, nothing has turned up. I know Rockin' Robin. They have a drum that I want, but is overpriced. But thanks for the tip. I'll certainly give them a call. It appears to be a very cool place.
Thanks again.
