Steve, mine was welded to the rollers and to the sides of the roller casting.
I had great difficulty as well, but manged to save my cross tube by sacrificing the roller and casting. I cut it into pieces.
The steering had been removed to use the carrier as a trailer. That's why it was welded.
Note the difference in the hole layout.
This is the pre universal carrier style which fortunately for me, was later adopted by the Australians in their LP2 carriers.
The differences being 1. used UNF thread. 2. The pin is drilled for lube to the bushes.

Arie, you should remove the cam plate (with the floor plate) first.
I found the left side casting to be more accessable to a grinder. There is still a lot of struggle involved. It would be much cheaper to freight two side roller assemblies than a cross tube. I would guess you could buy the side roller asemblies from one of the Canadian guys.

Good luck with your struggle!
