Spohn Tq Arm: Lost instructions

its installed but i forgot how to set the pinion angle.
i have the angle finder. where do i set it? on top of the rear end/torque arm? what do I set it to? something like 2 degrees?
also what are the torque specs for the various bolts in the kit? right now i just have everything tight, but im not driving it.

thanks!

PS: steve...so far i have got nothing but dropped jaws when my car buddies see the torque arm!

Here's a few sketches I did awhile back (fortunately I saved it). This will explain different ride height settings.

Important note: Rear axle must be loaded completely with car weight before setting pinion angle- angle will change when car is jacked up and suspension drops out.

Below is 3 different examples of correct pinion based on three different vehicle ride heights- note that the rear diff is always 1* lower in the front than the trans tailshaft reading.
