I have a 1984 300TD. In between the two roof racks are 5 metal strips. These strips have plastic inserted in them. Over the years the plastic strips have shrunk to approx an inch from each end. Does anyone know the part number for the inserts, the metal strips themselves, or how the metal strips are attached. If I cant get replacement inserts, I might just take them off and repaint the roof.
