I think we've found your problem. Get the alignment done first and if it still isn't working like it should then start looking elsewhere. When I rebuilt my front end I eyeballed the adjustments the best I could and I still managed to scuff up my old tires just driving a couple miles to the alignment shop.
Try to find a reputable shop with someone who as experience doing alignment on cars with torsion-bar suspension. Even if they haven't done an old A-body Mopar the setup is pretty simple and there haven't been too many variations of the torsion-bar setup over the decades.
