I've found this diagram:

I'm assuming that I need the following fixings:
2 x 15/7
2 x 6/16
1 x 17/18
There are other holes in the spoiler that no fixings listed for, do the existing bumper fixings fit through these holes?
What are the left and right 'coverings' (3 & 4), are they required? And also the 'air channels' (19), do I need these too?
Cheers,
