Skip to contentHC Mopar 55-66 Model 70 rear seat - pattern required
Mopar produced a rear seat heater core and listed it as Model 700. To confuse you further. a Model 700 front heater is mounted to the firewall . These are both Model 700s and this is the REAR Seat heater
We require a pattern or a heater box to construct this heater core.
We do not keep this heater core in stock & will need to fabricate it.
Our build queue varies.
Made in the USA of copper and brass

We make to order. Please allow adequate time for us to build.
