heater box question

[69 charger man]

well my 70 charger org. came with ac... and i was just planing to do an eng. swap, but decided i would replace the floors and shes all apart lol...   well my question is can i just buy a non ac heater box to replace my ac one, even though i still have the ac firewall or should i just put the old ac box in even though i do not have all of the ac line stuff....

thanks ray

I can't answer your specific question about the heater box swap but if you would like to have working A/C you can purchase factory air conversion kits from Classic Auto Air. These kits replace all the factory A/C hardware under the hood. The condensor is optional. I just ordered one of the kits for my 70 Charger R/T. The total cost for the kit with shipping was $583. The kit includes a new Sanden compressor all the other needed hardware and hoses. Their web address is www.classicautoair.com

Back in the 80's I converted a 69 with air to non-air. I got the heater box out of a 70 Belvidere sedan. I had to fill up some holes on the firewall and I can't remember exactly, but I think I had to drill at least on mounting hole and one heater hole where I filled in a larger a/c hole. I'm sure someone else will chime in with more current experience.

the firewall & heater box are totally different , I would just use the AC heater box
