not sure I understand what your problem is. Perhaps this photo will provide some clarity for you.
if my memory serves me correctly, you should assemble the unit as pictured prior to installation
The shift lever bottom ball should index between the two black hardened “guides” at the very bottom of the cage.
The clevis at the tip of the shift linkage rod will attach to the shift lever with the bolt through the two brass bushings
hope this helps just a little bit,
Larry
