Front end not level

The heads of the bolts are about 1/2 inch apart. Measuring from the floor to the wheel well.
did you loosen the lower control arm pivot nut, the one that is on the front side of the k-member, PRIOR to adjusting the torsion bar adjusting bolt? That is absolutely necessary. Of course, when you are done adjusting the ride height, then you must retighten the LCA pivot nut.
