Lower rear air deflector

The Cadillac ATS has a small air deflector in front of each wheelhouse. On the front, you can Google 20931825 and see the left side deflector. I have searched all over the Internet for the part number for the left rear deflector, which is smaller and can be seen on the forward side of the rear wheelhouse. Both of these parts are broken on my car, and I would like to eventually replace them. I just can't find the rear deflector anywhere on a GM diagram, it's like the part doesn't exist. Can anyone out there help with this part number? I have never been in a situation where I could not find a part number.
