69 Camaro heater conversion
I'm building a 69 Z-28 clone from a standard 350 air conditioned car. I want to replace the air conditioning system with a standard Camaro heater system. Can anyone give me some leads as to where I can find all the parts I need to make the conversion. There seems to be lots of air conditioning parts available, but not much for the heater car. I'm aware there will have to be some firewall mods for the heater unit.
Thanks for any help.
