72 duster AC car, heater core removal

I also have and AC car here with the dash out That car also has a couple of units setting inside I kept for reference. I am going to put AC in my Demon From this car so I can also provide some reference pictures if needed. I have a factory shop manual I can scan pics and pages for you if needed. I just orderd a Non AC kit from Detroit Muscle Opened the box yesterday they give you everything. Don't start your project without the kit for AC.
