Steering question.

How far off center? "A" body? At top of column, steering wheel attaches to shaft with a master spline. Is it correctly installed? At bottom of column, the shaft is attached to the box again with a master spline. Is this correctly installed? Pitman arm is attached to the box with a master spline. Is that correctly installed? If all parts are correctly installed, then you need a front end alignment. Probably you will need to shorten the turnbuckles on one side and lengthen them on the other side to point the wheels straight ahead.
