Here are some pics of the rivets and bushings. The original bushings are shown for comparison. The new ones don't resemble the originals BUT they fit both the hole and the shaft and they're black.

To install you have to remove the handle, drill out the rivet and install the bushing from the back so the spring holds it in and doesn't push it out.

Bushings are 20 cents each Rivets are 10 cents each.

PM your requirements till May 15th - I ship the week after.
