What should the pinion angle be on a 73 dodge dart sport thats an A BODY trying to set up rear end so it hooks good **(*)
Angle is measured relative to crank/trans centerline or a line perpendicular to it, not the ground. The reason 5-7 was quoted is because you have a leaf spring car. The extra angle is there for spring wrap when the axle is under load (acceleration). Ladder bar cars are 2-3 degrees and 4 links are 0-2.
