I would suggest getting the hood scoop you like the best, and then taking it and the car to a good body shop. That's what I did, they asked me if the coating they used was ok, and initially I thought it would be, but I don't like it anymore. Just tell them to use fiberglass or plaster to blend in the edges, and/or coat the whole scoop. its more work, but it will pay off in quality. another tip is to use a tape measure to get a general idea of how long the scoop will be on your hood.
