I'm taking my replica CTR wing to get modified, painted, and installed this week. I need to know exactly what to tell the body shop to modify. Sorry if I sound clueless, I just don't want my car to sit in a body shop all week. Thanks a lot.

1) Which holes need to be shaved? A, B, C, or D? Then the holes should be filled in and sanded, correct?
2) Should I use double sided tape to keep the wing more stable, and/or prevent rattles? If so, where should I apply the tape?
