1966 Barracuda A/C question

65 Dartman said
According to my 65 literature, they offered the integrated heater/AC in 65. I have 2 65 Dart and 2 65 Valiant factory heater/AC bezels. Definitely not knee-knocker.

All had under dash ducting fed by the firewall mounted box.

I believe they are referring to the ducting assembly being under the dash instead of thru the dash as other manufacturers did.
