Heater box??

I just did a factory a/c conversion on my 69. I have a template for the firewall & some experience in doing it if you need any advice or pictures. For $25 I would buy the a/c section for parts. They are not repoping the vacuum diaphragms or a/c evaporator coils, so parts are hard to come by. Most people took the a/c’s Out rather than put them in
