Help with Heater & AC Control Assembly

How is that a "dial"?
Those heater controls are EXACTLY the same as my 69 Barracuda, and I put a CAA AC kit in mine. If you follow the instructions carefully (It looks like they finally updated them), your current non-AC controls will work great. Don't bother jury rigging a fix around it!!!!! After about 15 years, my system still works great.
