[FC] FC gas heater

[corvanatics@corvair.org]

Hello, all.  When I purchased my 63 greenbrier deluxe, there was a complete looking gas heater.  There is the control assembly with the cables,a long exhaust pipe, a blower assembly, and another big assembly (in truth it's been stored away and I don't recall exactly what it looks like but it's bigger than the blower.) How can I tell if it's original to my van or if it is for a car? Is there parts numbers I can check? Is there a good photo online of a fc gas heater? Thank you, Matt Toni
