Yes. All cars with CAP have the crankcase breather ducted to the air cleaner, but not al cars with the crankcase breather ducted to the air cleaner have CAP.
This hose became standard on all cars later. I don’t know the year of the change.
The ducted breather first appeared on all '64 California-sold cars, and spread to all cars in '68 when CAP became standard equipment regardless of what state the car was sold in.
