Who makes a copper heater core for the GMCs?   We do.  If you are searching for an obsolete, one-off or hard to find copper and brass copper heater core 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."

Our build queue varies.
