So you will want to get the pinion to be 2.9 degrees up.
That 2.9 degree up should be while accelerating right? Not at rest since the pinion will rise as you give it gas? So you'll want it slightly less then 2.9 up at rest?
Yes, that would be the ideal point. As Dayclona said, may be 1 degree different at rest vs. acceleration; so about 2 degrees up on pinion at rest.
Remember, as acceleration increases, the "G" forces and suspension loading slowly decrease close to "at rest". The initial movement of the suspension is greatest at the beginning point of acceleration/ "G" force . Just a small amount of difference at rest will get you close to where you need to be. If you can find out what the factory used for pinion up degrees and tai lshaft down degrees, I would start with that and makes adjustments if needed
