I need to order a standard 70 gas cap for my Mustang and NPD shows a nonvented without evaporative emissions or nonvented with evaporative emissions. Its an original Ill. car 4/70 build date. How do I tell?

Thanks

Does it have a Smog pump on the engine?

IIRC, evap emmission equipment was on Calif. cars only in 70.
