Ok, now i see where your confusion comes from. You've owned two of the three available wheel arch versions, Trailhawk, and AD-I. The AD-II has a mud flap that i'm afraid will need to be removed, leaving behind the holes the mud flap used for mounting. I hope that the rails will fit without needing to remove the mud flaps, but if they need to be removed, i'll have to buy new trim. i haven't been able to find the part number for the trim yet or i'd show you a picture of the trim without the mud flaps, you'd see two holes. i took the following photo and tried to get the same angle of your pics to be apples to apples.
