My 1947.2 Panel Truck has a Door Weatherstrip Lower Retainer. Does the door weatherstrip go all the way around the door like later years? Or is there a different profile weatherstrip for the bottom of the door? Does this Door Weatherstrip Lower Retainer just mash down the weatherstrip? The profile of this retainer seems to have a crumb catcher. That makes me question what kind of weatherstrip goes here. The FAM indicates there is a different piece there. I could not find that from any of the vendors, does anyone sell that? Here is a picture of the door with the retainer, a picture from the FAM, and a picture from a weatherstrip supplier.
