location of twin hood scoops on 1970 Duster

I have a 69 dart I just installed a pair on. Yes 69 dart did not come with hood scoops. So there were no semi circles under the hood to start from. There are quit a few threads about dual hood scoops and there location & installation.
I used pink ratan paper taped to the hood and started from there . The scoops turned out strait and I drilled the cold air 4 1/8" holes near the back of the hood scoops instead of the front. I like the way they turned out.
