Thanks!
Not much except for this one:
Pretty much just cut the lip to shape. Mark 9 evenly space holes on the lip(about 10cm's apart). Pierce holes with a knife and thread a zip tie through each one. Position lip against car and drill a small hole(just enough to fit zip tie) through the 9 holes you previously made, and into the body of the car. Thread the zip tie in and over the grill.
Hope that helps! Can take more pictures tomorrow if needed.
