Setting pinion angle

i have a 67 dart with a 383/727 combo. the rear suspension is

cal-tracs with mono leafs

inboard springs and rear sliders.

i have a new moser housing going in and i want to set the correct pinion angle. i have read alot on the subject and think i have a good idea of how do do this. i plan to jack the car up and place it on ramp under all four tires leveling as needed to level the lower rocker panel. the trans should be tilting down in the rear some place in the 3 degree area correct? so if that is correct then i would want the pinion pointing up 3 degrees also?

this is where my question comes in. if the trans is pointing down 3 degrees then rear is up the 3 degrees to make a parallel line. which way does the 3-5 degree go on the pinion to compinsate for axel wrap?


it seem that i should point the pinion down 3 degrees more to compensate for the axel wrap. that would put me at level. any help is greatly appreciated. im having a hard time wrapping my head around this.
