Thank you Dodge71Demon and Pishta for the picture and diagram. My Dart does have a 8.25 like the diagram, but there is NO plug on the cover. What year 8.25 diagram is that? I looked again and there is a round steel plug on the passenger side of the carrier. Cannot put a wrench on it like the picture. There is a square hole in the center of the plug. Looks like a 1/2" drive socket wrench would fit into the hole. If I could take a picture and figure out how to upload picture to a Chrome Book I would.
