Steel Guitar Builder

I saw this question had been posted before, but no answer. I need some of the above bushings. They are 1/4" OD, 1/8" ID (or slightly larger, the crooked end on the pedal rods is 1/8"), and the have a small shoulder on one side, and snap into the hole. Any ideas? I'll take 8 (at least) or more if I need to. It's hard to see, but one is pictured below. I can take a better pic if needed.
