I agree with Y-Blockhead and Brian T. The reason this adjustment is needed is that the steering arm on the left front wheel has been bent somewhat. That will also affect toe out on turns as well. There doesn't seem to be any way to measure this without a spec. measurement of "ball to backing plate" distance. If the drag link end is threaded on one end only, the adjustment would only be in increments of a single thread count (single revolution). An adjustment for sure, but often you'll be caught in the position of needing a 1/2 turn. Quite a number of other factors can also cause the offset in the sweet spot of the sector and worm. A truely adjustable drag link would be a good thing but having the ability know if the steering arm is spot on would also help avoid issues. Also, I believe that the steering arm had a design change ie. early and late - another issue if it was to correct a toe out on turns issue.
