If you plan on using these aftermarket units a good tip would be to do this job before you and the car retire for the night. Your thinking whats that got to do with anything? Well before you snap them into place, place a very small thin amount of Dow Silicone caulking on the inside lip. Carefull you dont need alot. Just the corners where they snap. Twenty four hours would be better but you should be able to drive without fear or worry about them letting loose, after 12 or so hours. You will never see or notice this and they should stay put.
