The basic instrument cluster is the same other than the heater only controls and bezel and the AC controls with its own bezel. I can dig my. Ezekiel our tomorrow for a picture. Do you still have all the underdash stuff? A friend compared 65/66 The heater part to a 67 or maybe 68 or so heater unit and said they were the same. The early A AC part with the evaporator is for 65/66. The later units don’t fit. 65dartcharger restored a 65 Dart wagon with a 273 2 barrel with AC and PS and gas many photos of his restored engine compartment. A friend of mine probably gas extra hoses from the firewall to the compressor and compressor to the condenser but he is - as he said in another post - in the land of sun, sand and fun - in Afghanistan till late April or so. I can take pics of everything if needed although nothing has been installed.
