What is the caster...sounds like some postive castor would pull it straight. If you now have power steering...on a light hot rod...might need a little positive caster to make up for the power steering.Of course "toe" could also contribute...but I would verify caster first.
Yes..I would use a magnetic digital gauge to check housing tube vs axle faces? If you had run out..I would think you'd have a vibration issue.
Can they give you a print out of the front alignment ?Solid axle rear, not much can be done except maybe swap a unmodified rear in, maybe Ford 8.8 or other. Could the steering be tight (like not returning to center) ?Mine does this after using a stabilizer.
What about the front to rear weight ratio? Maybe there's not enough weight up front.
