It would be interesting to see what the factory PS alignment setting recommendation was.
But I would think it should have more neg caster on the right, and equal camber.
FWIW, and it's a different steering setup, my Duster drag car (Jack Arnew-modified) runs about 7 deg caster and goes straight as a string.
But you wouldn't want to stick your hand between the steering wheel spokes when the steering unwinds...
