63-66 a body ac options
Any early A with factory air (with the integrated heat and AC controller), the underdash units fit quite well under the dash with virtually no loss of legroom if you have a bench seat - no loss with buckets. I have found that Unless you have a complete donor vehicle the same as what you have, then typically the hardest part to find is the heat/AC bezel. 65 and 66 Darts are both one year only. 65 Valiants and Barracudas one year only. 66 Barracudas and 66 Valiants were each there own model for the bezel! I decided early on in my wagon build I want factory air so I am using the factory air firewall, underdash assembly and had my compressor and drier rebuilt by Classic Air. I am using R12 as that’s what the system was designed for to provide maximum cooling. When converting to R134 Classic Air told me they could make the adjustments during the compressor rebuild and provide a replacement 134 compatible condenser at extra cost. The tech said With 134, Extra cabin insulation should be added as well as tinted windows and would be helpful even using R12
