Hi! I just bought a 1988 325i convertible. :driving The piece that is missing, is a silver plastic cover (about 3 x2 inches - more or less) that sits between the rear window and the convertible top cover (when it is down). It is supposed to be attached to the car via 3 small plastic plugs. Does anyone know what I am talking about? And if so, do you know what to call it?? I have been trying to search online, but have had no luck.
