I just did some bushing work on my old 19mm Weltmeister front bar.
The bushings are not quite the same as the ones shown for 22mm.
I made new out of delrin, which is probably not the best material for
this but the huge bearing surface should make it okay for most uses.
The dimensions you need are 1.505" long, 1.128" OD, 0.752" ID.
No lip on either end, the piece bolted to the fender well has a stop on
the inside. As others have said, there is some room for the bar to
move sideways, so be prepared after pushing the arm as far as it will
go, to have a small spacer to fit in-between the bushing and arm.
“As a bushing material, delrin boasts many important properties including high tensile strength, high impact strength, high elongation, high chemical resistance, low moisture absorption, and more. In addition to low deflection, delrin's best feature when compared with polyurethane is self-lubrication.”
