International 1941-1949 Heater Core

HC International 41-49 - requires pattern

Regular price $359.00

To construct the 1941 to 1949 International truck heater core we will reuire your pattern.

If you are searching for an obsolete, one-off or hard to find copper and brass heater core for your older vehicle you are not alone and you may be 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."  If we do not have a pattern you may need to ship yours in.

Our build queue varies.

Made in the USA
