The Stovebolt Site Forums The Shop Area Driveline knuckle spindle hub questions

I'm in the middle of trying to figure out how to move forward on my 1955.2 GMC 150 (3/4 ton 8 lug)

I am having the same issue as a lot of people and cant find a good way to get rid of the outdated front wheel ball bearings

My questions are
1 is the knuckle and spindle cast as one piece or is the spindle pressed into the knuckle???

2 has anyone tried to have a billet hub or spindle/ knuckle made to fit a more common bearing?

3 or lastly a different knuckle that could be adapted to fit?

I want to keep my 8 lug wheels and swap to disk brakes.
