<!doctype html public "-//w3c//dtd html 4.0 transitional//en"> <html> <body bgcolor="#FFFFFF"> We install tons of PianoDisc systems which require major overhaul of the original trapwork for installation.  Everything except the shift lever is removed and replaced with retrofit parts.  Over the years for whatever reason we have been saving most of the parts we remove.  The end result is that we have a couple of huge boxes overflowing with trapwork levers.  Not long ago we disgarded several additional boxes due to space.  We have all kinds of trapwork levers from a variety of different pianos.  Levers, pitmans, pull thingys, push thingys, up thingys, down thingys, and hundreds of springs.  I may be able to provide you with something that will fit.
