Hey Kiner: I got the same type cowl induction hood for my 72 cuda and it was the worst fit and finish you could imagine.
In the back of the underside where the hood is supposed to contact the rubber seal, i had to remove about 1 1/2 inches and fiberglass it back together so the hood would close. It is warped up (has a bow in it at the fenders center).
the body guy did a good job smoothing the top of the hood and did a great job painting it. HOwever, pop ups keep appearing in the glass. I did take it back after about 8 months and had it repaired and repainted. Now, after about 2 months, i have two more zits coming out of the glass.
If you have a complaint, they will not even want to talk to you.
