The original hoods are made just as the corvette pieces were. They are press molded. Meaning that both sides are smooth. The hairs are clearly visable just as a FRP (Fiberglass Reinforced Polyester) panel from a mid sixtes to 71 corvette panels are.
If you would like you could post or e-mail me pictures of them. And I'll compare them to the original hood I am restoring. I might be able to help you make a better determination if they are real.
