As an option, it wasn't an option on the other three cars mentioned.Yes, I do believe it is in reference to the N96 fresh air package and not the A12 cars with the fiberglass pin-on hoods, however, the question was referring to the 1970 car line up.
I believe there might be a fourth car, the 1970 Coronet R/T with 440 Six Pack appears to have been available without the N96 option?
