It is possible to lift the steering rod without loosing the bolts. I am thinking about replacing the steering shaft bushings and adding a 1" shim to the cap steering part #A33147. And replacing the ball as the support bearings are unavailable. What is your idea?
If you can't get parts to fix what is there, I'd remove it completely. I would then fabricate a new mounting bracket and bolt on a new pillow block bearing with locks.
