71 Scamp NASCAR style spoiler???

It all depends on how the rest of the car is done. In your very first picture, it looks beyond stupid. Wheel covers on the stock wheels with stock tires. If you want a real opinion, show us the different styles on the car as it is going to be. As long as everything else on the car matches, it will look ok. I say ok because it's not my cup of tea. But so what? It's not my car. Do what makes you happy with it, but unless all the other accents on the car match with the same common direction, you won't pull it off. Look at the one in post #26. I'm not even a fan of wings, but that looks pretty good, because the rest of the car MATCHES.
