Wheel allignment

I did the 75 disc swap onto my 70 Dart, and at the same time installed new upper control arm bushings, upper ball joints and lower ball joints. Put everything back together, and put wheels back on it, and adjusted the torsion bars. Brakes work fine but as soon as you drive it even a few feet the wheels go on funny angles and whatnot. Is that just because I haven't gotten an allignment yet? Will an allignment fix that problem?
