WANTED: R1100S main stand bolt + nut, right side

[oyster]

No idea how this may have parted company, but that is what I am seeking.
R1100S right hand main stand fixing bolt; it might be the same as the left side.
It is a M10 X 30 countersunk bolt into a threaded top hat bush. I need the bush/nut.
REALOEM shows a main stand, but the mountings shown do not match my bike, so ordering from a main agent is out.
I am aware of how rare a main stand is, however....

What year bike, is it your 1999? Early bikes have 18mm bushes later have 20mm.
