I am trying to take my front bumper off and the damn scrivet heads are stripped. The dealership must have did that after installing my grille a while back. Anyone know how to pop those four that are on the sides ontop of the grille if they are stripped? I tried a knife to wedge in and pry the suckers out but they wouldnt come out. I also used a flathead screwdriver and no luck. Is there anything I can do besides taking it to Lexus?
