ok i posted a thread tryna figure how to install the center caps on my ms after a 2 days and a late post now i got it each wheel has to be removed and the metal clip goes in the center from the inside to where the clips stick out the front then mount the wheel back on once lugs are tightened and wheel is set the caps pop right on make sure all 4 clips look the same and not bent if they are usually get some pliers and adjust i had to post since everyone here can read and not post so wala there you go.
