This fits the 1947-1948 Chevy Trucks With Outside Air Heater and Defroster and 1950-1952 Chevy Trucks with the Airflow Style Heater and Defroster. THE TUBES ARE INLINE.
The "Air Flow" DeLuxe heater used fresh air supplied from a duct that took in air from the outside. The lower priced heater was the "Recirculating" heater used the in-cabin air and had the round donut style core. Its 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. devestechnet.com provides an excellent visual how-to on restoring the heater core in a 1950 Chevy Truck.

We try to keep this heater core in stock; our build queue varies but please allow at least 3-4 weeks for production time.
