Ok, just redid measurements and its as follows:
Engine: 1.5 degrees tail down relative to ground
Pinion: -2.5 degrees pinion down relative to ground
Driveshaft is 3.7 degrees tail down relative to level
i think you are close,pinion should be -1.5 degrees to the ground,cass always told me set pinion opposite of trans and roll it down 2-3 degrees and your done
