How to check Driveshaft Angles?
What tool and operation do you use to check your pinion angles? I have a BMR Trak Pack and am actively fabricating the transmission mount for my 4L80E. I want to make sure I get the angles of the driveshaft right. I heard the one you get from BMR or SLP [the little dial ones] are horrible and wanted to know how everyone else was doing it. I can shim the tranmission as much as needed and adjust the rear two ways. Thanks.

What are the angles you guys are using? What's the driveshaft angle? I know to keep the from and rear within 1* of each other, but I also know not to make each more than 3* overall.

Copied from the instructions from my UMI chassis mount TA:
Place the angle finder on the driveshaft and record the angle. Now place the angle finder on the bottom plate of the torque arm where it attaches to the rear end, record this angle as well. To achieve true pinion angle you must add the two measurements together. For example if the driveshaft measures 0 degrees and the TA measure -1 degrees, you have a -1 degrees of pinion angle.
Hope that helps, I was in the process of doing this and had the instructions handy.
