@Brian, hard to find item.
I was and am after one since months. Got no reply in this forum. Later I found a used one here in Germany with the same faults as everytime - surface and broken turnlights brackets...
Happily I just had still two NOS ones. Now its only one left for my restoration...
But did you know these items? Part #92022-1230 seems to stabilze the brackets. I used these many years before and the brackets getting more solid when daily use the bike.
The one which was sold on the bay was rather expensive, I think.
Repair your bracket and use those wahsers...
Cheers
