You will be turning 'Tie rod adjusting sleeve'. This is located between the inner and outer tie rod ends and changes the length between the drag/center link and the spindles/knuckles. Adjust them equally to keep the toe the same.

Since you can turn further to the right, you want to shorten the right side and lengthen the left.

I agree with 1rippen6's idea of going lock to lock, counting turns, and finding center. You can do this looking at the steering wheel and the angle of the pitman arm. Steering wheel should be about 3-3.5 turns lock to lock

I had this experience in my 97 Suburban. I cheaped out and bought a $25 pitman arm rather than the $45 Moog one. Turns out the cheap one was keyed 1 tooth off, so the steering wheel was like 45* off. I used the method I described to get it close. Still a couple degrees off, but it drives fine.
