Adding an aftermarket Hood Scoop help needed

OK, as for whether the scoop is a little modern then the car the answer is yes. Ive seen a few with this type scoop on and I like it. Heres a couple pics of what drove me to this style because originally I was going with a more era correct style scoop.Scoop.jpg 66-1.jpg 66-4.jpg
Now heres a pic of the underside of my scoop. I need to make a pattern and then find an original seal for the bottom.
