Not available elsewhere. The 65 hollow stud is shorter than the 66, which is sold by others. Also, it is located in a different position that the 66. In 65, it is located in center carb.passenger side, rear. If your A body has air conditioning, the hollow stud is a vacuum source for air conditioning. I believe it is also used if you have a factory vacuum gauge. All the full sized Pontiacs used the same vacuum sorce for activating the heater controls. Perfect repro down to the correct bevel on the top of the nipple. Zinc plated, silver.
