Quadrajet Carbs

[Danny Ashley]

The way to tell a 1974 and earlier reman Quadrajet is to look at the vent hole behind the choke plate. They drive a "T" , used to retain the accelerator pump check ball in a Rochester 2 bbl, in that hole to prevent installing the air cleaner stud in it. When I see that I move along because I know it will have mis-matched parts and some of the other modifications Alan pointed out.
