1966 Hollow Stud Tri-power Engine Compartment or newer Pontiac 2 bblExcellent exact reproduction. This is not the repro hollow stud other carry. Even has the correct bevel on the edge of the nipple, silver zinc plated.. Should be located in the center carb position, passanger side, rear. Used on GTO with air and all full sized cars supplying vacuum to heater controls. Some add this stud to supply vacuum for vacuum gauge.
