I'm using the harmonic balancer to get the engine/trans angle and I'm easily able to get the pinion angle with a straight edge on the pinion flange.

Right now with the engine down about 2.8* and the pinion up at about 1.5*, that should give me a pretty even 2.8/2.5 equal but opposing spread under load. With the driveshaft up towards the pinion, the working angles are bigger than I'd want, but they are now better at around 4* at the u-joints.
