[quote]They worn parts in my shifter weren't washers, they were shouldered plastic bushings that were a very tight fit. I highly doubt that you're going to find anything at any hardware store that will work.

I recently did this repair, and I did find a substitute for the plastic bushings in my garage, however, my garage does look like a hardware store.
I don't know what they were from, but a small amount of filing, and the shifter was as good as new.
