I'm starting the Demon dash restoration and don't seem to have the correct parts for the heater controls. The car started life with air conditioning and is getting converted to non air. I have found the non air dash frame and woodgrain bezel, but seem to be missing the correct controls. The original A/C bezel has the description of the controls molded into the face. the non A/C bezel has a hole for the control to come through. I picked up non air controls but they must be for an older model, they wont fit into the opening. anyone know what I need?
