Newbie w/ Dash question

I am fairly new to the Camaro world.  I have a recently acquired 1972.  I have purchased a new / replacmenet dash bezel and I do not know how to remove the old one, (this is the black & chrome plastic part that goes around the gagues).  I have removed the screws,...but it is still held in by the headlight switch.  What do I do next??  How do I remove the switch?  Do I only have to remove the "stem"?

Go to www.yearone.com and order a catalog from them for $7. It has colored, breakdown drawings of alot of the dash components. It also has alot of parts if you need them.

look behind the light switch button and there should be a small notch cut, take a straight screwdiver and put it in the notch and there should me a little piece of metal push it down and the knob should come right off.
