Head Light Switch

[Cruzinlow]

This is my first post of many to come I started to disassemble my dash on the 65 c10 this weekend and couldn't figures how to remove the knob on the headlight switch. I'm thinking it should just pull off but I gave it a tug and it wouldn't budge and I didn't want to force it. So is there a trick to getting these off?? On a side note I have a inline 292 3 three speed trans with over drive can anyone tell me what it's worth???

Thanks
