Removing heater knobs on a 409

I'm in the process of removing my dash and I'm wondering how to remove the two heater control knobs. I see two holes on each knob and assume there is a pin holding them in. But before I start pounding, I thought I had better check with someone more familiar. Thanks in advance.

Yes you assume correctly Larry, there is a pin in each of the holes that has to be removed first.

John, how does one remove the "pin" ?

It appears there is a spring-loaded retaining pin.

There is indeed a hexagonal shaft with a spring loaded pin on the 411, which you need to push in - I used a small allen key to do so. See attached photo.

I assumed the 409 was different given John's comment about removing a pin.

Got them off. Thank you! I assume the two smaller knobs are removed with a simple screw. (mine are corroded away).
