The holes are for steel line clips, which must bear the centrifugal

So, line the holes with SS grommets/hollow rivets.

It would even "look cool", with the grommets indicating that someone
had done something about the wear issue.

The holes need to be spaced 100 mils apart, and the hole in the grommet
couldn't be less than 50 mil, and 1/16 is better. So it'd need to be a
pretty teeny grommet.

Any suggestions where to find such?

Stainless POP rivets? Install rivet, pop, hit the back side with a
grinder to smooth them off.
If you want the back to look pretty use a cupped grinding point to dress
them.

Or use the rivet heads and a press to form the back. Could even spin the
back side down.

With a 1/16" shank, and a head (and hole size) smaller than 1/10"?
