I looked at that site for the 1970 383 and 440 dual snorkel air cleaners. It is ambiguous as to whether the paint is a smooth black or a crinkle black. Which is correct?
In the 70's, I had a 70 Challenger R/T, 383 magnum and a 70 Challenger R/T SE, 383 magnum. They were both were completely original cars and they both had crinkle black dual snorkel air cleaners.
