Get in touch with Woody, itsnotanova, and see if he can cut that part out of a car and will ship it to you. He doesn't ship large body parts but that might be small enough. I don't know if it would end up costing more than a whole floor from the dealer. You can check out whether or not that piece is separately available in the PET here -
