These things are like hens teeth, got one anyway:
I also have the inside cover from a R1100R along with the rear brake system, unfortunately the only wheel I have that will fit it is from the same R1100R, but it'll have to do till I get a spoked wheel.

I've ordered the Phosphor Bronze pivot bushing from Rubber Chicken and whe that arrives I'll bolt it all up and see how my alignment works out.....
Next photo should be of the bike complete with disk brakes on the back.
