I found this in the back of an old Ram Charger. It is new and from what I can tell it has never been installed. The guy I got it from said it fits a K5 Blazer. But I looked them up and the examples I found on line look nothing like this. So, because it was in the back of a Ram Charger I figured it would fit one of them. Same thing, the examples I found on line are different. I cannot locate any part numbers or even a manufacturer on it anywhere. Anyone have any ideas?
