To add to this, the no number open frames I have seen are the six spoke variety like the 927s and 928s. The 69-70 open frame alts I have seen on birds, Olds, vettes have a 5 spoke open frame. Also, I have seen aftermarket new chrome alternators also using this 6-spoke open frame.

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.
