I have some older hi hat cymbals with small holes. I would like to make them work on my more modern hi hat stand(s), without enlarging the holes.

I have the clutch covered (an old Gretsch clutch that seems to fit fine on the newer stands.

However, the bottom cymbal won't fit over the plastic base, as the plastic tubing is too fat. Is there a replacement base piece available with smaller diameter center tube, that would fit on a newer stand? I have two stands - a Gibralter and a Tama (both single-braced).

thanks!
