[Mgs] Gear shift knob

[WSpohn4 at aol.com]

Barrie, the shift know thread isn't a critical structural issue.  You  
might consider drilling the hole just slightly oversize so that it clears the  
root thread size on the shaft, and then see how far down it fits, and if not 
far  enough, run a correct tap in.  Even if you hash the inside threads a 
bit,  they will often thread on enough, especially if you (lightly) fit a thin 
lock  nut under it.
 
I know it sounds like butchery, but it often works in that specific  
situation, and saves a bad situation when there really isn't enough meat to be  
doing major machining without harming the knob.
 
If you do drill it out, you might want to try doing it on a drill press and 
 holding the knob in your hand wearing a rubber glove.  Of course if it  
catches (which it WILL if you apply much pressure at all) it may fling it 
across  the shop, so doing it inside a cardboard box is advisable, but I've had 
luck  doing this very carefully and it doesn't risk making marks on the 
outside of the  knob..

Thanks  for the many responses.   The difference between the knob and  
gear sift knob is very very small.
