Heater Box Assembly for 1964-1965 Mustangs with a 2-speed heater motor.
The heater box assembly consists of the front and rear casings with doors. This is a factory type fiberglass two piece heater box/heater core casing. The heater box is a pre-assembled unit which includes the gasket and all seals. The heater plenum attaches to this assembly and directs warm air to the car.
Heater box was difficult to install as one of the screws that hold the electric motor was bent during shipping. I had to repair it and it was difficult to line up. When compaired with the origional it is a cheap import.
