How to install this Hemi hood scoop

I came across these photos while trying to find ways to get this hood scoop on. He seems to have the same scoop as I do.

1- he cut the flanges off.
2-he then glassed in little tabs to put bolts through.

It seems as if hes just gonna lay it on top, bolt it in, and then glass it in to make up the difference in the gaps and to give it a smooth look.

I feel like this might be my easiest option on doing it the right way. I wish I could have bolted it in but its just not laying flat.

What do you guys think of this idea? unless anyone has a better idea. which i hope someone does hahah
