In 1983 was there 49 state and California cars? I see in a porsche factory parts catalog in the model descriptio they only list 1978 and 1979 as having (CAL). The 1980 thru 1983 don’t have a (CAL) version, only a
(USA) listing. My smog sticker on the Smog / Line Diagram says EPA. The Tag on the “B” pillar also has no mention of California version, only USEPA.
