In the daylight I can see there appears to be some scoring of lines on the shaft where the gears go through it, and the surface inside the gears is mostly smooth but my finger can feel some irregularities. The shaft absolutely will not go into those gears by more than the first 1/2 inch. The shaft will easily go into the carrier and pin in place. I left these 2 gears out and put the pin and lock bolt back in the differential to hold the assembly together so I could put the truck back on the wheels, and move the truck around the garage on its roller skates. One of the axles is fused to the brake drum and I can't break it free. That is a minor inconvenience. The major inconvenience is the axles are 17 spline. I researched that and it was in 12 bolts for just a couple of years, 63-64. I was pleased to see I don't have pressed-on brake backing plates, they are held on with 4 bolts. 5-lug conversion axles are not available for 17 spline. I think I need to change out the stuff in this differential to get going with better condition and 30 spline.
