Thats the filler plate I have, its big enough for a plate but not a frame. Are you sure some frames will fit in that gavity?

 

I see there are 2 filler plates you can purchase for the 2008 Audi A6. A grey and a Black one. Which one will match the front grille? The Grille looks black but can also be considered dark grey. My car color is Daytona Grey S-Line. Any help would be greatly appreciated. Thanks.
