My power steering box adapter plates move the steering box 9/16" to the left. This is the absolute minimum that the plate can be. The difference in the turning radius, as a result of upgrading to power steering can easily be compensated for by offsetting the steering linkage back to the right. This can be done when you have a front end alignment, which is a good idea after you make a change such as power steering, and/or disc brake upgrade.
