if you want one that looks correct please take the following under advisement;

- 1967-1970(49 state) Pontiac Quadrajets pretty much all look the same;
The biggest visual difference between these years is the lack of (67-68), or presence of (69-70) the rectangular front fuel bowl vent cover.

- The 1970 Pontiac California carbs are a little bit unique, but are near dead ringers for 1971 Quadrajets.

- 1967-1971 Pontiac Quadrajets all use a bolt on throttle cable attachment.

- 1972 Pontiac Quadrajets are near dead ringers for 1971 Pontiac Quadrajets, except they are the first ones to have a fixed throttle cable arm on the throttle arm.

- 1973/1974 Pontiac Quadrajets look very similar to the 1972 Pontiac Quadrajets, except they have an attached hot air choke mechanism.

- The first year where Pontiac Quadrajets came standard as the 800 cfm units was 1975 - those look quite different from the 1971-1974 Quadrajets.

- Pretty much any pre-smog Quadrajet can be made to run like any other, it mostly comes down to fuel metering, and how air/fuel was mixed.
