If that scoop mounts similar to the other one Paul sells I have installed two of them.
You cut out a hole the size of the outer edges of the scoop where it will just fit.
Only cut through the top layer except where you need to cut through where the opening goes.
Then you bond pieces that overlap the edge to where the scoop, when layed in the opening, will be even with the surface of the hood.
You can use screws to temporarily hold the pieces in place.
When it`s even it makes it a lot easier to keep the fiberglass and filler smooth.
Here is when I did mine.
Unfortunately, I didn`t take a lot of pics. http://www.fiero.nl/forum/Forum1/HTML/097072.html
