Help with 7 tooth steering rebuild

[mack4759]

I am in need of some help rebuilding my 7 tooth steering box. Disassembly was pretty straight forward but now I am not sure how to approach the rest of the rebuild. Looking at the pictures I bet you cannot guess what kind of lubricant was used by the previous owner. Hint, it was not oil. I imagine I need a new worm and sector gear, but I am not sure what to do about the steering shaft. The shaft is chewed up above the worm gear, can the shaft be built up and turned back to specs? I am also wondering about the bearings, as you can see in the picture there is a lot of clearance between the bearing and shaft. Same with the shaft and lower bushing, the clearance at the bushing is due to wear from no lubrication, but I cannot see the bearings wearing like that, are they the wrong size? Do the bearings sit on the knurled part of the shaft?

I would appreciate any insight on how to approach this rebuild. Thanks for your time.
