I want to remove the dash gauge cluster from my 2002 V6 Mustang ragtop but I
can't get the headlight switch knob off. The aftermarket manual I have says
to use a small screwdriver to press the tab in the slot of the knob shaft
and pull; and there is a slot in the knob shaft with a visible metal tab;
but I have tried unsuccessfully on several occasions to get the knob off. I
have pushed that little metal tab forward, backwards, in, out, down and even
tried pulling on it with forceps, but the knob won't budge. Is there a
trick to getting this darn thing off? Any tips?

Thanks - Squidly
