You will have to be more specific. By "speaker cover" I suspect you mean #23864 as shown on Interior/Door Panels. If so, we need to know if you have manual windows vs power windows, and manual vs power door locks. Also, I think all of those will be Rosewood, but I'm not sure of that, so please tell us if that is what you need.
As for the "seatbelt covers for the shoulder belts", I don't know which pieces you mean. Can you give us the number from the illustration on Interior/Seat Belts? And, what color?
