so i found the back parts of the rear seats so far, the fit comfortably because of how snug they are, they cross bar helps the back supports, the hooks that they clip into are upside down so they sit higher and flush with the back of the seat. i found some front i plan on picking up next week, and so ive heard you can use the same rails as the p10 and they fit perfect, but they are electric, or at least mine will be, wire em up and have electric black leather interior!!
