I could do with a slightly higher gear shift, that is, higher off the ground.  I notice on the linkage locknuts on a threaded shaft.  Very few threads showing.  Is this an adjustment mechanism?  The service manual seems silent on that matter.  It would be logical.

Thanks!

Thanks.  That's what I figured once I looked at it, but I'm upside down in the parking lot at work.  Not the best working environment!

  Look at the threads you can tell which way they turn to loosen.
