you're only looking for a appx 2* difference between the d/s and the pinion flange. so for example, if the d/s angle is 0. and the pinion flange is down -2*, you have your 2* difference. Like stated above, you want the pinion angle to be (-) because when you launch, the pinion will want to rotate positive.
From what I have read, with a 1-piece DS you should measure the difference between the transmission flange and the pinion flange.
