I'll look for the knobs this weekend and will let you know. Pretty sure the knobs are the same for A/C and non-A/C (I'll verify that with the 2 cars I have) and I'm certain that I saved them from the 2 cars (1 of each) I parted out 25 years ago, question is whether I can find them.
As far as price, not really sure what these are worth. I'm more of a 67 Plymouth part collector, some say hoarder, than seller. Not looking to get rich, but don't want to give them away either. I'll try to do some research this weekend and come up with a fair price.
Should be able to ship them pretty quick once I find all the pieces and we settle on a price.
