I have an original 1978 TAMA drum kit with the original TAMA cymbal stands. These are the only things that work properly. The old white TAMA nylon nuts aren't available anywhere. I've tried all of the newer styles and different combinations of Gilbralter pieces, nothing works right. These fit through the felts down to the base washer so the only thing touching the cymbal are the felts and these. If you have a vintage TAMA cymbal stand, these are what you need.
