LP once said that "Air is Free, you can do all kinds of things with it". Just pick a photo and make it like the one you see. Heck, I have seen him change spoilers and wing size and shape during one race night. If you try to do a replica of LP's car for one season, you would have to build around 30, they were never the same race to race. Choose a photo and run with it--------Moment in Time build. Even if you make up the shape, chances are he used it once.
