I agree with what GT289 said about a professional alignment. I was suggesting doing it at home over the usual chain store that has mostly worked on strut cars. There's been more then once someone here that have had the shims fall out because they didn't tighten the control arm bolts or completely ignored the owner's specs and set it to stock. It's a good way to learn. Honestly my first alignment was meant to be a quicky so I could do a shake down drive. I did't spend too much time but did get it pretty even side to side and the car drove great. The steering wheel was straight and the car tracked straight. It didn't pull to either side. I ended up leaving it for a year.
I'm not a complete idiot, pieces are missing.
