This fits the 1949-1952 Chevy Cars and Trucks With Fresh Air Heater.  

The Fresh Air heater used outside air supplied from a duct that took in air from the outside. The lower priced heater was the "Recirculating" heater that used the in-cabin air and had the round donut style core.   It is most commonly found in southern "mild climate" cars.

We have replaced the cellular Harrison design with tube and fin core that can handle the higher system pressures of today's engines.  

Our build queue varies.
