Alignment specs

Not really. My '62 B body is aligned to original factory specs and does not wander around on radials. The steering and front suspension parts are new and the steering box had been adjusted up. It makes the manual steering a lot lighter.

You indeed have to get used the the sensitivity and lack of self-centering force of the steering with the slight negative caster; it certainly does behave differently than a modern steering car with positive caster since the driver has to provide the centering action on the wheel. But it does not inherently wander, and this is in the Appalachian Mtns on curvey roads with road camber varying all over the place.
