Steering

[Craig's 71]

My 1971 Plymouth Duster when I drive it sometimes the steering wheel is straight and I drive and when I get to where I'm going it's off to one side or the other any ideas of whats going on the steering box is tight

First thought would usually be ball joints, but I'd bet it's lower control arm bushings or your K member is moving.
My car did that when I first got it and it was mostly trashed bushings.

Yep, I would say lower control arm bushings also.
