There could be a chance that the steering box was set up wrong. Most folks check this stuff pretty well when doing a steering gear repair. If the sector is off by one tooth, it would severely limit steering to one side or the other depending on how it was set up.

This may not affect model A cars but the end of the sector shaft generally has a master spline on later cars so that the pitman arm will only go on in one place. I've seen folks file on the master spine so they can put in on in any location. This can cause the same type problem. When the steering shaft is centered, the key way or master spline should be in it's steering centered location and the pitman arm should also be in its centered location. The same thing can happen with steering wheels that have a master spline. I haven't messed with an early model A that has a splined type steering wheel. If it has no master spline then it could be put on off center. It may be hard to tell on a Ford 7-tooth steering box.
