Deluxe heater from a 1956 Chevy truck. The fan is not frozen, and there are no rust-outs in the enclosure. I decided to go with a smooth firewall, so this heater won't work with that. I also have the controller and a GMC and a Chevy faceplate. The GMC faceplate is really hard to find.
It's getting cold, and maybe your truck needs a heater?
Heater Box: $70
Controller: with GMC faceplate- $50
with Chevrolet faceplate- $35
