This concept of " locking the steering box'... I am not sure all cars have that option. Not all steering wheels are adjustable with regards to the splines... I have seen them with a spline missing, which made it only one installation position.. the splines only being for stregth of connection. So I think some will have to rely on turning the adjusters and looking at the steering wheel to get all in accordance. I don't know how Larry does toe-in.... but I do not believe the concept of being able to set them at , for instance, your 30 degree turn example. They do not remain in their straight ahead relationship or they would really wear out tires....
