1939-1941 Chevrolet Super Deluxe Heater and Defroster Harrison H-140. This model's housing was also used for GMC and Willys Overland with changes to trims and badges.
If you are a purist, you will probably want your round Harrison cellular heater core restored. The trouble is, the replacement cell cores without tanks costs ~ $340!
Because most people just want their window clear of fog, their feet warm and their wife happy, we scrapped that idea and re-designed the heater core unit. The tube and fin core design can handle the system pressure and has a 5.2" 12V SPAL fan with 313CFM. We kept it all hidden inside the same round housing and did it so we would not break your bank.
We make to order and build queues vary.
