on the drivers side near the headlight its a little loose I can push up on the bumper and close the gap. I took off the wheel well splash guard, but I couldn't figure out what in there would tighten it up there is a bunch of plastic with screws in it that are unaccessible with the bumper cover still in place. I really don't want to deal with the stealership if I don't have to so does anyone know how to tighten this up?
