Anybody that wants to attempt this needs to be fluent in bump steer and Ackerman. Swapping the factory ball joints side to side will toe the wheel inward during a turn, not good. Make sure that Caster is set in the build 1st. Caster affects bump steer as well. Rack width depends on outer tie rod location. Proper outer tie rod location for optimized Ackerman needs to be established after establishing built in caster. But before rack width selection. In the end the steering arm outer tie rod location will be set with Ackerman and caster correct. Then the inner tie rod (socket joint) can be located in a parallelogram looking from the front using the outer tie rod, lower ball joint, inner control arm pivot, inner tie rod.
