I would forget about the pivot, that was a 6 cyl operation prior to 56. None of those parts are going to line up with the Saganaw side cover which has a complete different configuration. Locate a 2-3 shift rod from a TF truck as well as the shifter box mentioned previously. It will likely have to be bent to fit as well as the 1-R shift rod. It can be worked out, it will just require some "modifications".
