Pinion angle and drivetrain vibration

Your description is fuzzy. Are you saying that the pinion pointing towards the engine is UP?

-Rear end pinion: -1* down towards rear of car

is what you said...........

What I understood from that is that both the trans and pinion pointing at each other are up?

Don't worry about the driveshaft. Pick a reference like "level" and compare the trans and the pinion. The two of them need to be as close to parallel to each other as possible when under hard acceleration.

When at rest, the pinion FRONT point towards the engine needs to be "down" in relation to the engine / crank/ transmission centerline
