I've got a brand new set of these, still in the package:
http://www.gibraltarhardware.com/?fa=partsdetail&curcat=2&bnd=11&cid=104&sid=463&pid=1580
I just don't need them.
They're like sixteen bucks + shipping everywhere...
How about $10 plus shipping? Or I'll trade em for some heads, mallets, percussion or something...make me an offer.
(they fit those new, anxiously awaited, Ludwig A.T.L.A.S. mounts...)
