Does anyone know if the heater box in the '77 and earlier Hornets is the same as the '78 and after Concords? I need to rebuild my heater box and I am having difficulties finding gaskets for the Concord.
AC or non A/C?
The car has AC.
From what I can tell AMC used the same heater box thru 1980. I see it does separate from the A/C box, so that is good.
