I have searched for a PN for the screw that is under the rubber piece on the metal door sill plate.....there is only one very small screw. I have looked on the parts diagram and it doesn't show this screw. Thank you for any help
AFAIK, there is no screw under the rubber FERRARI insert in the door sill. The sill is glued down to the rocker panel below and has 3 screws along its side into the lip where the carpet terminates. There are several threads on Fchat describing how to remove the sills. Just do a search.
I think there is a screw in some cases, put there by a previous owner or dealer to help hold it down while the glue is drying. I was tempted to do that when I put mine back on.
