Here is the real deal on 49 state US distributors from the beginning of time.

All early - 1987 have mechanical advance. Curves vary from year to year.


Early - 1968: Xtra small distributor, vacuum advance (correctly called "non-smog", also sold as "non-USA").
>li>1969 - 1974: XS distributor, but w/ vac retard.

1975 & early 1976: small distributor, completely redesigned, very good quality points distributor. Vacuum retard.

Late 1976 & 1977: Same, but w/ vac advance

1978: redesigned w/ Med. size screwdown, waterproof cap, electronic ignition. Vacuum advance & retard.

1979 - 1980: dual diaphragm advance. One big advance stage for normal operation, small second stage for extra advance at hi-altitude

1981 - 1987 distributor body redesigned to use large cap. Same dual diapragm advance introduced in '79.

1988 - 1992 distributor redesigned w/ out advance. Distributor pickup is a crank angle sensor, advance curve is controlled by computer.
