If you are searching for a copper and brass heater core for your 1930s Oldsmobile then you are in luck. We make our own cores and fabricate our own tanks so, naturally, we get asked to build custom heater cores or "small radiators." 

We require a housing be sent in to make this heater core.

Our build queue varies.
