Will a 65 Dart Non AC Heater fit into a to 66 Dart with AC Heater? Any mods needed to the firewall?
65 Dart Non AC Heater to 66 Dart with AC

If all the underdash HVAC components are removed, it should bolt in. You will also need the non-AC controls.
The AC blower motor is larger than the non-AC motor so the firewall opening for the motor is also larger. You’ll need to Fabricate some kind of adapter to fill in the difference between the two. You’ll need a plug for where the evaporator lines come through the firewall.

If I remember correctly, the bulk head wiring connector is turned sideways on the a/c firewall . Not sure if it has to be done that way to clearance the hvac unit
Due to the interference with the slant rotating rod throttle system, the factory HVAC-equipped 65/66 A Bodies needed to use the V8 cable-style throttle which also resulted in rotating the bulkhead connector 90 degrees for clearance. If the HVAC system is swapped for a heater unit only, it won’t matter about the orientation of the bulkhead or gas pedal

If you can modify the firewall I guess anything is possible . the blower fan is in the wrong position as well as the size is different . Swapping controls is needed . My question is "Why". an aftermarket heater/defroster is a lot less hassle and is 100% more efficient .

I understand that even within the 1965 year, the bulkhead varied significantly between AC and non-AC cars. Modification requires a lot of cutting and patching. Some have replaced the entire firewall. If you have a 1966 AC climate box and don't want AC, why not just open it and remove the evaporator?

I still have it and I will consider that too. It's so dam bulky I cut off the AC part, but a little welding and fabrication should make it work!
Will you sell me the AC unit and assorted accessories for the AC!!!!!!!!
