Alans scoop did not come with the holes in the side. I think they must be something to do with the louvres in the NADA bonnet.
If you wanted to fill them, simply use chopped strand (fibreglass bridge gap) and place filler over the stop. This is the stadard procedure with fibreglass repairs.
To cut the hole, you need to do the following.
1) place th e scoop in position, measuring that it is in the correct position against the 2 original bonnet buldges.
2) Draw round the scoop with black marker.
3) Mask around the inside of the drawn template with 1" masking tape - keeping the tape as straight and neat as possible, especially around corners
4) Then draw around the inside of the masking tape with the balck marker in a neat and straight fashion (this is the line you will cut)
5) Remove the masking tape.
6) Using a cutting disk, cut a line at the top, bottom and both sides to give you space to get the air saw in.
7) Cut the hole with an air saw.
8) File down the edges.
9) Drill 6 holes either side of the cut where you will place you screws ------- making sure they are in the middle, as the recess on the scoop at the bottom is about an inch, which you will screw into.
10) PLace the scoop back in position, sticking it down with double sided number plate tape.
11)Drill up into scoop to make mark where you have to place drill holes in scoop.
12)Drill holes in scoop off of car.
13) Paint edges you have cut and drilled on bonnet with etch primer to stop water getting into bonnet and lifting paint.
14) When scoop has been fully etch primed, primer filled and painted in body colour, and painted matt black underneath to match bonnet underside, place a very thin bead of seam sealer all the way around the outside of the scoop.
15) Place scoop in position, using small alan key or pop rivet, locate holes.
16) Screw the scoop down and clean off excess seam sealer.
17)Under the bonnet, paint the screws black and dust over wit h good quality matt black paint (MIPA in a can is fantastic)
Job done!
