Cockpit Heating

Hi Sean

Search online, look for heat exchangers, they come in all sizes.  They are much less cost that a used car heater core.   An Amazon search online has tons available.  

Cheers

If you buy something called a heat exchanger, be sure you're getting a water-to-air type.  Many are dual-circuit water-to-water type and are not open to airflow.  There are lots of cheap heater cores on Amazon as well, but the problem with online purchases is that they're all listed by car make and model, not by dimensions.  Getting one in person allows you to measure what you're getting and know that it will fit.

If I were buying anything from an auto wrecker, I'd look for a late model car that had taken a rear end hit.  Anything from an older car may have had old, acidic coolant sitting in it for years, and anything from a car that took a front end crash could be damaged.
