66 A-body A/C - Heater box and controls

Hey Gang- Happy New Year!

I have the 66' apart and I am looking for a good (rebuildable) a/c -heater box with the controls for my 66 Barracuda. I thought about going after market, but if I can find a rebuildable a/c box for mine- Id rather rebuild it than the plain heater box with an under dash unit banging my passenger's knees.

Any help would be good. I was told by a few people to look on craigs list for a southern car.
Here in New England , cold air was 2X 55mph. Looking to remedy that since "global warming" seems to be a real thing. I just saw a polar bear in shorts drinking a Coke on TV. LOL!
Thanks,
Joe
