Well I've had a bit of trouble with the linkage split pin, it kept vibrating out but luckily somebody had put a different one in at some point so it was slightly longer so out came the tap and die set:
Then the finished product: (ignore the shite paste round the zorst joint)
Finished opinion no play at all in the stick and it feels nice and tight to change gear again so its been a win win situation as the pin had a small amount of play beforehand.
Cheers for reading
