There was a guy on a car forum that I used to be a member of that made polyurethane shifter bushings. Good quality stuff. I bet he, or anyone else could make these out of the same material.

 

Teflon is a plastic.
Being a machinist I have worked with a varity of plastics.I think I would try making them out of Delrin,Turcite or any harder plastic.Even a type of bronze may work.

 

If you are planning on marketing these, I'll step up and be first in line to try a pair... [sm=goodidea.gif]
