Rebuilding a heater box is hopefully something you'll only have to do once. For that one time you choose to complete it, do it right.
Begin with the correct heater box for your make, model and year. This one will fit a 1968-1970 B-Body Mopar, in this case, a Dodge Charger WITH AIR CONDITIONING.
There is a big difference between an A/C box and one without A/C. They are not interchangeable.
