just back halfed a 74 duster for a fellow drag racer . narrowed 8 3/4 32in by 14in tires.i have set pionion angles before but this is the first time that the pinion center line is higher than the trans center line ,the pinion angle is 5degs neg or in the nose down position the drive shaft angle is 2deg positive or up position because the trans is 3/4in lower than level center of the pinion . this is a ladder bar suspension so is the pinion angle neg3degs or am i reading this wrong. thanks
