Impex is is pretty good. I think this is the part you're looking for, and only ~$50 or so. You might want to check your plastic side skirts for damage (~$50 each), and be sure you have all the torx screws and speed nuts, and the spider washer thingies that hold the side skirts to the car.

This is for manual trans. If you have an auto trans you're SOL - they're $200+
