Just so you know they are re popping them now.
Megaparts and Dodgeboy is a no go...and what Megaparts had was for Dodges and A/C and heat, no 4 button heat and cool.
Sorry wish I could have helped
I'm going to ask a question in he hope that someone smarter than I can answer it... There seem to be a lot of period correct A/C switches available, with that being said if you don't install the A/C selector button and have no electrical connectors on the A/C terminals why wouldn't it work?
I have Anthony powell phone #There is a guy in Texas that rebuilds them completely. I believe his name is Anthony Powell. I'll look up his info. PM me.
