Only after, but whatever. Get over it. Main reason I gave you shit is that you put the same damn thing in two different places.
Now, onto your question.
Yes, they are two different scoops and the main reason you cant find much on it is nobody has done it. Welcome to the wonderful world of having to figure something out for yourself, everyones been there at one point or two.
My thoughts for you, I, myself, would start with the opening between the ribs on the underside of your hood and center it, make a template that you can use to transfer the mounting holes over to your hood.
My biggest advice for you, measure alot and then measure some more. You can only cut/drill once.
Good Luck.
