S500 Coupe Speaker Grille
 

Some idiot kicked the uppermost speaker grille on the passenger door of my '96 S500 Coupe. Its cracked in several places and needs to be replaced.
I don't see any obvious method that this grille is attached to the door and don't want to pull on it until I'm sure how its attached.
Anybody know? Do I have to take the door panel off?
I've looked at the procedure for removing the door panel and its just slightly less complicated than launching the space shuttle.
Thanks in advance. KenP
