Underdash A/C

Unless you want an underdash AC unit I would check to see if anyone builds one that is "hidden" behind the dash. Classic Auto Air makes one for the Dusters and Demons, Dart Sports, not sure about other models. I see there is a great thread posted in reply #6 above. Everything in that is current with the exception to the controls. They have updated the controls now so the cables are eliminated. Instead you install potentiometers to the control head and everything is electronic from there on out.
