Tool C-4044 is for pushing the steering shaft down and out of the upper bearing with the steering column out of the car.

You can easily make a clone tool for about $1 by just buying an #8-32 all thread rod and cutting 3 pieces about 4" long. Screw these into the housing, put any small 3-slot puller plate over the threaded rods, add washers and #8-32 nuts, and push against the shaft with the center bolt of the 3-slot puller. If this isn't clear, holler, and I'll try to take a photo.

As you can tell from the puny #8-32 all thread rods, very little force is needed to push the steering shaft out of the upper bearing. To reverse the process (I guess that's tool C-4113? It was C-3879 in my 69 FSM.), you just need to push against the upper bearing inner race while pulling the shaft upward. Should be able to do this with a short piece of tubing or PVC pipe of the right diameter to cover the upper bearing inner race and pull the shaft by turning the shaft nut against a big washer sitting on the top of the tube. Before making a tube of the right diameter and length, try pulling the shaft upward through the bearing with one hand while pushing on the bearing with the other hand, just to see if that's possible.
