You’ll need 1/2-ton lower control arms.
Then of course, 1/2-ton balljoints, and everything from the spindles out.
Outer tie rods will be different also.
Finding a donor truck or parts is a good idea, but you’re rebuilding the suspension and brakes as you go.,,, so you will need done new parts also.

If you find a good donor truck you can swap the suspension and resell it. I did this with a 3/4 ton Suburban and a 1/2 ton Suburban.
