Another detail on the shifter knob set screw: The tip is unthreaded (turned down smaller than the threaded part) and goes into a hole on the shifter shaft to positively locate the height of the shifter so the lockout release works properly. When you first loosen it, you'll be able to feel the knob move up and down a tiny bit and you'll wonder why it won't come off. You just need to back the screw out a little more until the tip clears the hole. Once it clears and you can slide the knob freely, stop unscrewing it so that it stays in the knob so you don't lose it and have to mess with getting it started back into the threads.
When you re-install the knob, once the screw is rubbing on the shaft as you lower the knob, feel for the tip of the screw to hit the hole, then tighten the screw a little as you make sure the tip is going into the hole, then tighten it up.
