The original wings are pretty strong. If this was an aftermarket wing it would have flew off. Also the repops sag in the sun. They should have a crown looking at it from the rear I had one on my Demon also. Still have it. I like the gull wing on the Demon and Duster it matches the points on the quarter ends. My 71 roadrunner is also getting one. I have a bunch I kept from cars I parted. I sold all the go wings. They belong on a 69 mustang.
