I am wondering if anyone has found a suitable replacement for
the thin-walled fiber bushings used in the pump pedal linkages
of Auto-Pneumatic and Auto-Deluxe (Autopiano) pump pedal linkages.
The originals are made of compressed fiber, and I haven't been
able to come up with a replacement part of the correct diameters.

Has anyone found or made something that works?  I suppose other
modern materials like Nylon would be fine as well.
