So I'm removing my dash pads, radio, etc, etc, so I can repaint the dash in the dart.

I cant seem to get the knob off the headlight switch.
Am I missing something ? The knob should just pull off right ? I know to remove the switch you unscrew the chrome bezel at the base, but the knob has to come off first.

There is no setscrew in the knob that I can see, and I've pulled on it as hard as I dare and it wont come off. I'm worried about damageing the switch if I pull any harder.

Any ideas ?
