Here is a no name heater box I bought at a swap meet last summer for my current project, but it doesn't fit. The box fits into a 10" x 10" x 10" area with the core hose connections and the mounting bolts outside of the area. The metal housing is in good condition. The heater core holds air pressure and flows freely, it looks really good. When I bought it, it came with a new fan motor, but it was the wrong shaft size (wrong motor not included). The original fan motor there, the wiring is breaking down bad, the motor may or may not work. I have removed the fan blade and the squirrel cage from the motor shaft without damage to either. The unit has been put back together in the proper order, but will need dissembled to tighten the fan and squirrel cage set screws and address the motor wiring. The unit comes with a small under dash panel with a cable and blower motor switch. The cable is free moving, I did not test the switch. Also included is a water cable operated shut off valve. The valve works freely and holds air pressure through its range. You get it all for $50 OBO, + shipping. PM me here, Gene
