I should have mentioned, in my original post, that I have the 40-7222 shifter housing. It's different from the 68-7222 shifter housing. I also have Van Pelt's book but he focuses on the 36 and later transmissions. I can't find a picture, like the one above, for the 40-7222 shifter housing.
The kit that 3rdgen sells works from 28-37 shifter tops, so the pic of the 36 and newer that's posted should show how they are assembled. Its just two plungers and a spring in the center. No balls until the double detent setup.
The shape of the shift tower from 1932 through 1935 had the angle sloped toward the rear but they were a single detent set up like the 1936 up to 37 or 38 which has the straight up vertical shift tower. The later ones were double detent types.
