The pilot plate angles, hole diameters are fine. Yeah 3/16" should be fine.

As I've said before the adapter plate hole can be a a small amount larger than the pilot plate.

The pilot hole should be kept "tight fit" but not interference(press) fit to starter.

This allows "fine tuning" of pinion/ring gear clearance within the tolerances before welding it to the adapter plate. (especially if no access to a laser cut or cnc).

With a tight pilot hole, removing/replacing the starter wont require any readjustment and allows you to maintain pinion/ring gear clearance(tooth contact depth) within tolerance of .020"-.030" suggested by most starter manufacturers.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
