Hi Greg, if you are still looking for a mount give this guy a call.
I sold him the mount but he has never used it. I think he wants about £30 It's a touratech and I used it for 2 years excellent piece of kit.

I did discover a few alternatives, but having seen the Touratech item in the metal, I decided to go for that and emptied my wallet at Bracken a few days ago!
