A body shop supply store would be a good place to try looking for something like this-they often have a huge selection of oddball screws, and sometimes let you buy them per piece when you only need a few.What you could do is get some slightly longer screws .With bigger heads and use them or get some longer screws and washers.
Another possibility is finishing/cup/trim washers.
One might have a large enough diameter to catch and hold the edge of that overlay cover in place without looking too out of place. They are thin steel with a fairly sharp edge that has the potential to grip and not slip on a plastic surface. You might get lucky and find some at a place where you can buy just a few.
