Thanks!!! thought it might be something like that. Good advice and I agree no more going to the 'normal' alignment shops for me.Adjust the drag link. Alignment shops are pretty useless with a solid axle vehicle.
The drag link runs from the pitman arm (on the steering box), to the PS steering arm, on the front side of the axle. There are two clamps on each end, holding the drag link from rotating, captured by a bolt/nut which are both a 17mm. Loosen them to the point the drag link can rotate. Longer will move the steering wheel to driver (left), shorter will move it to passenger (right).
Usually I leave the clamp loose, maybe hand tighten, then take it for a test drive or two, figure out where I want it, then go from that. The wheel will move a lot from a full rotation of the rod, so it’s best to do small, incremental adjustments until it is where you want it.
Or stop caring. Mine has been off for months. Seems every time I get it just right, I bend the drag link and have to replace or straighten it, starting the process over.
