I personally would cut that front piece out and get some black mesh from the hardware store and fit it in the opening. Just fold the top edge at a 90 degree angle and use some double sided tape to hold it to the scoop. Fold the lower edge over on itself (behind it so it's hidden in the scoop), or just another 90 w/o the tape, to get a nice flat, un-sharp edge to rest against the hood surface. That is what they do with some of the quarter window scoops that come with mesh inserts.
Similar to this:
Or you could buy almost any color vinyl off ebay and cut a new one yourself...
