Mike, you have to have some way to get the tires to turn in dissimilar arcs as you turn and it's done by intersecting the lines drawn through the center of the lower ball joint and the outer tie rod ends, then running that line back to the rear axle. That will give you 100% Ackerman. If the lines intersect behind the axle somewhere, it's less than 100%. If they intersect in front of the axle somewhere, it's over 100%.
