I bought a matte grille from Jlevisw.com and installed it today. Very easy to remove and install the kidney grills, except for the left one (broke 2 clips off but still holds pretty snug) It didn't line up well so when i removed it and i broke one off from the middle, then putting it back on i broke another one, but now its all lined up better.
I got the same problem with the screws for the top plastic parts not coming out or going in. I got the black ones on and and they wont tighten up. I got one out and cleaned off the blue sealant they put on the screw and it went in like a charm.
Make sure to remove the Blue sealant on the torx screws before you put the top parts back on.
