I've got one of those pivoted c-spanners in the garage - actually it is Mark's as it came with one of the shocks he bought. At least I think it's still there unless he took it back.
Glen, I'm around all weekend if you want to pop over on the bike and see if it works? I've also got a nice aluminium rod that would be ideal for use as a drift if not
Give me a call to check I'm around.
