Hi Tony

I imagine all American piano parts suppliers carry them, unless you're 
looking for the manufacturer.  I get them from American Piano Supply Co. 
(APSCO), Box 1068, Clifton, NJ  07014-1068, USA; phone 973-777-3600, toll 
free (US only?) 800-457-4266
fax 973-777-0481; www.americanpiano.com.

If you've dealt with any other suppliers here they probably have them also.  
Good luck.

Bruce
