Looks like you have the tools and space for the task. It's just parts, the right parts help. Not so long ago I went through similar with a broken front axle.
The difference between the original and the replacement meant I had to machine a new steering cylinder. Fortunately, I'm equipped for something like that. (Lathe, mill etc.)
When I put the snow blade on the antique Fordson, I ran the push bars all the way back to the rear axle. Including relay plates at the mid mounting pads. Breaking the casting is not big on my list of things I want to mess with. Though I have split that tractor twice in the 45 years I've had her. It's a wet clutch on the Fordson, so the throw out bearing should outlast everything else ;-)
