This is a Firestone heater core.  We made it for a Studebaker Champion c.1940 and immediately had a call for Ford Truck with the same.,  It turns out Firestone was selling these as an aftermarket for a variety of makes and models.  The image with housing is just for reference.  We do not have housing available for sale; only the heater core.

Our build queue varies.
