I'm sorry, but is parallel to the ground considered 0 degrees? so you adjust it 5 degrees up from that? I'm just a little lost Thanks

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.

How do you know the angle of the crank/trans center line? And once you have that angle, do you just adjust the pinion angle 5-7 degrees towards the ground relative to the crank to allow for leaf spring wrap?
