FYI it seems it was a mirror mount bolt on the 500, a frame bolt on the TZR250. Also was fitted to the mirrors of the RD50, held something onto a DT80 and the rear brake master of an XT600 as well.
This is where it fits on the 2MA:

It's part number 91026-08025 if anyone has some loose bags of old NOS lying around.
If i cant find an exact match, then I guess I'm after two of thems-that-look-close haha...
