How to setup correct Pinion Angle?

[Vandals909]

My suspension kit from Ridetech should be in soon. I plan to install it and then set in my motor and transmission.

I have a 71c10 and I have engine stands from a 73 c20 (believe to be the same frame stand ECE uses) and using dirty dingo Sliders

I currently have a stock trans-member. I will need a new one piece driveshaft made for the Ridetech coil over trailing arm cross-member as my truck was originally a long bed and had a 2 piece drive shaft. The Ridetech trailing arm member requires a one piece driveshaft.

So with me running a lq4/4l80E combo in my 71 with dirty dingo sliders which use a clamb-shell. What is the best way to setup and check the pinion angle? Should I use my stock trans-member or aftermarket?

Sorry for the long winded post.
