Here are a few pictures. In some of them, you can see pieces of black weather stripping glued to the piece. It attaches by sheet metal screws, that is what the holes in the piece are for. Where the weather stripping attaches, it appears to be galvinized, and the is a chrome? stainless steel? lip that runs just below the drip guard moulding. The one picturedif for the passenger side, I need one for the drivers side. I also did not see a part number stamped on it.
