Can anyone tell me what the name of this piece is? It is located behind the head rest and retracts when the top is up and folds out when the top is put down. It has a plastic peice that is attached to it. Somehow it came loose and apparently blew off and now I am without that trim piece but don't know how to research it because I don't know the name of it. If you know the name of it or better yet where I can find one for the drivers side, I would greatly appreciate it.
