I forgot to latch mine on the 65. I was only going 30 MPH (thank GOD) when it flew up. It didn't do anything to any other part of the car except the hood.
Needless to say, I now have a new hood. I really like the look of the stock hood in the black color that they ship it in. It has the holes for the F O R D . I have since put hood pins in, and am making it look like a vintage Trans Am car (with graphics and stuff).
