I called Proforged this morning to ask, because I'd rather find out there is a difference before taking it apart, then finding out.
The tech said '70-'72 E-body used a smaller sector shaft, after '73 it was larger.
By the way, I had also ordered a pitman for the Valiant I'm building, and it was a different part number from the E-body, so the A-body pitman is different.
