I've got a Slingerland bass drum with the cymbal mount but I'm missing the the "L" shaped arm / tilter rod assembly.
I thought I might be able to replace the entire cymbal holder with a modern mount that fits the stock Slingerland hole spacing?
The original Slingerland mount and arm looks a little flimsy and the prices for originals seem to be pretty steep.
I have a modern Gretsch cymbal mount (another stillborn project) and it's beautifully made and very strong looking but alas the hole spacing is different. I see Gibraltar, Ludwig, and DW make a bass mount cymbal arm.
