Dash Instrument Disassembly

[340Challman]

Trying to take my dash apart and need help with the removal of the trip meter reset knob and the clock adjustment knob. How do those bad boys come out of there? I see no screw or catch release. I gave them a moderate tug thinking maybe they just pull out, but no joy there either. So, what are the magic words to coax them out of there. 
Thanks.

There is a tiny blade screw inside the hole of the knob. Once you remove it, don't lose the screw!

Wow! That's a sneaky place to screw them on.  Thanks R/T's

Once I take mind off I put a piece of tape over the hole. Keeps the screw inside.

I find using an eye glass screwdriver works.
