I have a Fordson Major. My Steering Shaft Nut Assembly (the piece holding the bearings to the worm shaft)failed today and I need this tractor back in service. I was wondering if anyone knows where I can buy just the Steering Shaft Nut Assembly by itself. The shaft is fine. Also where I can find the steering gear shims for the Major. I have looked though all the parts cat. and they don't seem to sell them separately...at least I cannot find them.
