1931-1934 Chevrolet Cars and Trucks used an accessory heater core. The original harrison design was a honeycomb pattern film core. If youre a purist, we can make that. Alternatovely, we can construct a modern efficient flat tube core with high fin density at a reduced cost. All of it is hidden inside the housing. It's your choice.
