My late 50s Slingerland BD cymbal mount is missing the wing screw. I am attaching pics of one I pulled from the spur brackets. I'd like to get one similar to this one except maybe a little longer threads. The threads are 1/4-20. The wing span must be close to this one or it will hit the shell. The closest thing I can find at a hardware store is a thumb screw. If you can help me out, please let me know.
Many thanks in advance!
