Clean air package help

Yep, the CAP test program was on '63 cars, but it was rolled out on '66 California cars. Previous California steps were '61 (mandatory PCV, spread to New York in '62 and 50-state/Canada in '63) and '64 (mandatory closed crankcase ventilation, that is the breather cap ducted to the air cleaner rather than just open to the atmosphere -- spread to 50-state/Canada cars for '68).
