So, in the box of parts I got with my '47 was this heater. It is apparently one that was added on, but that's about the only information I can guess about it. Does anybody have any information on it? In a way, it'd be kinda neat to use it if it works, and there isn't much to go wrong in it. Mainly, though, I'm just curious.
According to this, it looks like a company named 'Arvin' made this.
Here you can see a few things. There is a set of ports on the left that I'm going to guess went to the defrost vents. There are the water inlet and outlet lines. There is also the wire to supply current to the fan motor. And you can make out what appear to be studs for mounting it to the firewall.
This is the heater core. Not much in the way of technological advances between this one and the one in my '89.
Here are the vents on one side.
Here are the vents on the other side, and the aforementioned outlet for the defroster?
