[Fot] authenticity

[Bill Babcock]

I never saw an air dam on a car until about 1972. As I recall it was a  
Brock Yates deal, and everyone thought he was nuts. There were some  
rudimentary wings and spoilers early on, but air dams are a late  
development of the aero age that started in the late sixties. Long  
after people thought about wings they figured out that the air under  
the car was important too.
