'67 Dart GT Vert Rocker Trim

Need some help identifying how to reconnect the Rocker panel trim with the car, after the front drivers side wheel decided to go in a different direction than the car. I have straightened the trim piece out enough to reattach, but can't figure out if I should attach the clips to the trim first, or attach the clips to the body first, then attach the trim to the Rocker?
Clips go on the car first!
