Alignment advice needed?

Sounds like a caster problem to me. Caster and camber are the only two things that cause a pull, and if camber is good, then that leaves one left. Toe in automatically sets itself once the car is rolling. All that improper toe setting will cause is scuffing across the tire and noise. There may be a geometry issue with the '73 big bolt pattern (I'm assuming that is 73 control arms and spindle/hub). Also ask the tech who perfomed the alignment what the thrust angle was. If a front wheel only alignment was done and the trust angle was off that could have made your pull worse. that's my $.02. Good luck gettin it fixed :thumbup:
