Quicksilver. I am not bagging on the car or calling it a fake, just observing. I have seen and studied ALLOT of original 64-67 hood scoops because I used to sell metal replicas. Most I've seen that looked like that one turned out to be fiberglass, but originals being thin/fragile aluminum, it's certainly possible that the center sway on that one was caused by heavy hands. In fact I have mint original aluminum scoop hanging here next to me on the shop wall to compare it to.
