bump steer sucks
the box on the outside of the frame ahead of the axle limits the right hand turn due to tire rubbing the box
the rack attached to the solid axle means there is a lot more weight attached that is unsprung plus the steering column shaft needs to do a lot of extension/retraction, so not awesome. power steering hoses also nee to flex a lot, like every time the truck goes over a bump
personally I would stick with the stock location and adjust the drag link and pitman arm so that the drag link is level at ride height. move the box outboard, move the engine to the right
money spent on a quality steering system that works is money well spent. funny if you think about it and compare prices for other items on the project. guys will hem and haw about some things, like a part for the foundation of the truck, but then not think twice about a few thousand dollars in wheels and tires or a quality sound system.
thats just me though
