You need a magnetic base dial level that reads in degrees. You attach the magnet to the face of the drive shaft flange on the differential after removing the drive shaft and you adjust the uppers until you have a 3 degree down angle on the flange - be sure the car is level on 4 jack stands that are under the rear axles and front A-arms.

If you don't have all those fancy tools.... The idea is to have the driveline and the pinion gear in a straght line when you lonch. So seeing how the rear end will twist somewhat when you take off, set the arms so that the pinion and the driveline are not quite straght, but at a slight V angle.
It's only one tool and it's cheap....................
