A set like just these arrived yesterday from a forum member (thanks Tom).
Rearsets are on now, just need to run a new brake line.
...and..... these pipes came in yesterday, I'm going to pick them up after lunch!
(remove for update below)
The fttings for the HD-style flp up pegs are bolted onto the Chainsikle mounts. I may just remove them, bush out the mount and replace with Jap take off pegs.
I'll look into the Baxter grips, thanks.
