What spindles do I need?

Yeah, they're pretty tough alright. I have seen a couple of crash bent ones, but, most of the ones I've seen bent were ones that cooked a bearing and deformed the stub. I don't know if it's caster or camber specs that the OP can't achieve, but, I would suspect strut rods, K-member, control arms, and frame rails before I suspected a spindle. We're assuming, of course, that the bushings and ball joints are all within specs.
