shocks

No; if the car can be properly aligned as-is and it drives well, it simply means that the chassis is probably twisted a little, from age or an accident. A frame machine may be able to square things up, for many dollars. Or, consider different (slightly shorter) shocks, but be aware that its possible to create a car that cannot go around corners very well if you lower it too much. Poor handlimg, increased bump-steer, increased turning radius and shimmy can result from screwing with the stock geometry too much.
