67 Cuda-turns sharper to right than to the left

The tie rods are the only possible answer, if you described the situation correctly.

1---Center the box by counting turns

2--The pitman is keyed, so if it's the correct pitman, it HAS to be right

3--It is possible to get the steering coupler assembled 1/2 turn off if it's been apart, this would put the steering wheel 1/2 turn off

So what you do is, you count turns, and confirm that the wheel is properly oriented.

Tie the wheel securely in place, then adjust toe and jiggle the tie rod adjustments until the wheels are straight ahead

With my "backyard" alignment, it's impossible to actually tell if the wheels are REALLY straight ahead. So I usually get the bottom of the weel "off" by 8" or so the first time around, have to go back and move both tie rod sleeves a little bit IE one "in" and one "out" to preserve toe, recheck wheel in a short drive, then last, recheck toe.

Crowned roads and manual boxes, of course, "move" this some.
