i am puting bar end mirrors on my bike and want to replace the clamps that hold the mastercylinders (brake and clutch) so i dont have the mounting post for the old mirrors sticking up .i found one for the brake no problem but the clutch has a shim to make the bar bigger for some reason . i could use another clamp like i found for the brake and just mill the id but it looks like it would be awful thin .i really dont want to cut the mount off of the stock clamp .unless someone out there has a spare that i could cut and shape how i want. any ideas out there guy`s ?M
