For the broken air deflector under the bumper, you have to replace the entire bumper. I did it, it was easy only about 6 screws. You will need to paint it but it comes primed and ready for paint and clearcoat. The paint and supplies cost about $70, I sprayed the base and clear coat myself and it came out perfect and is still good after 2 winters. Follow the link below to purchase a bumper for $150, the fit and quality were exactly the same as the OEM.

Good luck,

Jerry Mullen
