Dealer add on AC unit for 1970 Dodge Dart.

I have the "look alike" dealer add on unit. Has same profile and 3 vents as factory with its switches mounted in the blank fields between those vents. Pulled from a 71 Dart in 1990 after that slant 6 tossed a rod through the block. Laying around here since. I would need to check it out, power up its fan motor, before putting a price on it. It could be worth a hunert dollar bill.
PM me if interested.
