> Does anyone have any suggestions for a heater core,
Jim,
I used the system out of a '93 Mazda 323. The core is fairly small and
lightweight. I build a fiberglass heater box containing the blower fan, the
heater core and the AC condenser. 5/8 3003-3 al pipes will run the coolant
to the core. Pictures and details at http://kgarden.com/cozy/chap23g.htm
Let me know if you need any measurements.
Regards,
John Slade
