What sandman said,
but you should know that one end of the linkage bar - from memory I think its the gearbox end - has a left hand thread. So all you have to do is slacken the lock nut each end then turn the linkage bar to adjust. Once in the right place re-tighten the lock nuts. Couldn,t be easier.
Well it could - if the linkage bar was a hex instead of round!
