Default How to set pinion angle?

Long story short, I recently purchased a rear suspension setup from Founders Performance (well, mostly). Suspension setup includes the following:

UMI 2 PT Tubular SFC's (Bolt On)
Founders on car adjustable Panhard Bard
Founders LCA Relocation Brackets (Bolt On)
Founders 3 piece poly joint LCA's
Founders adjustable torque arm

Today, my UMI Torque Arm angle finder arrived unfortunately with no instructions on how to go about measuring, and determining pinion angle. I was hoping to get the TQ arm AND Panhard bar set tonight so I'll have the car available for the weekend. Can anyone point me in the right direction??

to set Pinion angle it needs to be at ride height with no more than 3 degrees negative with the relation to the transmission output shaft to the rear end pinion shaft

So, to clarify, there is no way to do this with the car on jackstands?

not really on jack stands your angle will be off a bit unless you get the car level on jack stands. i've seen people do it. I just took mine to work and put it on the drive on rack so i could adjust it while it was sitting on the ground basically but i work at a shop. Here are the instructions i got with my spohn torque arm.
