On each side of the boot support struts of the convertible, there is an adjustable screw with a tiny stick on pad that probably adjusts the position of the boot or the tension. The pad rests on a metal ledge. My pads were both coming loose. I glued them back. If they fall off, the metal screw would scrape against the metal ridge scraping the paint off and perhaps causing a rattle. I can post a picture if you can find them.
