1955-1958 MOPAR Model 702 704  Hot water Heater Core Series heater cores found in 1954, 1955, 1956,1957 and 1958 Chrysler, Dodge, Desoto and Plymouth. .  If you are searching for an obsolete, one-off or hard to find copper and brass 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."

We do not keep this heater core in stock & will need to fabricate it. 

Our build queue varies.

Made in the USA

Build time estimates [Feb 2025]

Brass/Black Model Ts

Our longstanding foundry (supplier) closed and all production was shifted to a neighboring foundry.  Apparently many of the closed foundry's workers were ineligible for rehire by the new foundry due to more aggressive immigration enforcement and the union has no employees to provide.  As of 2-20-25, we should receive castings in March 2025 and can resume production then. 

In the interim, we have been working with our one-off foundry to have pattern boxes made and these are trickling in in smaller batches and we will produce what we can.

Model As 5-6 weeks

Heater cores ~6 weeks

Model A and 32 Ford Street rods 6 weeks

Common street rods ~12-15 weeks

Tricky customs & complicated restorations ~16 weeks months

We appreciate your patience as we continue to recruit and train new fabricators and manage the labor shortfall our country has been experiencing.
