In response to Jim McCall McShop
That's all fine but bottom line is that you shouldn't go over +1 or +1.5º caster with manual steering.
To get 3-5º for power steering means you need aftermarket upper control arms, or that you must cut the front of the bracket where the upper control arm shaft is fastened from the frame, and move the front of the bracket about 3/8" outboard from where the factory put it. Then re-weld it.
Steering axis inclination is a function of how the spindles are machined and how the control arms accomodate that. In other words you can't change it without different spindles and adjusting the length of the control arms to match.
Increasing the steering axis inclination would be a good thing because it would lessen the "scrub radius" if you had wide wheels and tires.
