I only see a mechanical “catch” that appears designed to hold the top in place and a couple of reflections of the sun on the curved part of the trim and the corner of the top of the back seat. Maybe you could point it out with an arrow or circle or something like that?
Hi Charles, I am so sorry. I have no computer skills. If you went straight up from the left rear hubcap, and over about four inches to the curve in the trim, you would hit the particular shiny spot that I am talking about. If Paul Landis is telling the truth, it would have to be right there when Clint Hill is on the limo. Thank you very much for your kind reply! Sincerely yours, Michael
