Why do I have such sloppy steering?

My $.02, Speaking from experience with my 65 Barracuda, proceed methodically. First replace worn-out parts in your steering and frontend, then find an alignment pro who knows to dial in the extra caster needed for modern tires. After you do that, if the car still feels sloppy, then tighten the steering box in small increments. Don't over-tighten the box; if you do you will be all over the road and it can be downright scary!
