Anyone have the correct motor for this Arvin heater? As it was an aftermarket heater, hopefully someone would have a 12-volt motor for it. Or at least a motor you could take pictures of, so I know what to look for. The clearance between the back mount and the heater is 3 ½ inches. I looked at several on line and they are bigger than that.

Any help and photos are appreciated.
