Chevy 1937-1938 H-78 Twinflow Heater Core
HC 37-38 H78 Twinflow
Images of housing and support plate is for identification only. You are buying a heater core and 12 fan pusher for the 1937-1938 Harrison two door twinflow housing. The housing and support plate are separate items and not sold here.
If you are a purist, you will probably want your round Harrison heater core restored. However many of you may just want your window clear of fog, your feet warm and your wife happy. The 1937-1938 round heater cores are designed to fit the Harrison H-78 housing. Our re-designed heater core uses a better core design and a 12V SPAL fan. The thickness grows but we designed an interface that is not visible when installed inside the housing.
