Ackerman is a line drawn through the lower ball joint and outer tie rod end on each side of the car, so that the left and right side lines should intersect at the center of the rear differential. If the Nova was stock with a (not sure, but for instance) 110" wheelbase, then the Ackerman would be correct for that wheelbase. When you use a Nova front suspension system, but a longer wheelbase, the Ackerman lines intersect in front of the differential. Draw it out on a sheet of paper like I did to see it.
ackerman steering geometry is where the inside front wheel is steered in a sharper arc than the outside front in order to elimnate tire scrub at the inside wheel. checking that with the wheels sitting stright dont mean nothing that i can see
