Someone correct me if I'm wrong, but didn't the Clean Air Package for 65 in CA consist of the hose going from oil filler cap to the air cleaner? Non-Commandos/slants got painted oil fill caps with the nipple and painted air cleaners; Commandos and Hemi's got the chrome plated stuff. In 65 PCVs were installed in the cap that fit on the 2nd stovepipe. 66 and later the PCV was installed in a grommet on the valve cover.
