Sorry if this is a basic question. Doing the trunk part of my body work. The new floor will be put in place with some adhesive/welding in tomorrow. The old floor and others I have seen have a circular plastic piece near the middle of the floor. However my new floor from MB did not have this piece, just an empty circle. Just wondering what this piece is and what purpose it serves. Should I just take the one off the old piece and apply it to the new panel? Is this what other people have done.
