Remember, my observations are from a California perspective. During the '60's, California was more "progressive", (stupid ?), than some. This is why there are some differences in cars from other states. During these years, some shops were quiting smog certifications because the laws seemed to be changing daily. My car= 1968 cuda BB, who remembers the CAP valve? My car still wears one. Wasn't this a California thing? They had either a green cap or a black cap. Their purpose was to retard the vacuum signal to the vacuum advance during deceleration. More smog crap. Since mine is a restoration, it will continue to have one. They can be adjusted to non-op.
