You must have an open drive to be seeing the angle of the u-joints? If so,
what you want to do is take a protractor and place it on the yoke coming out
of the transmission and record the angle. Then take an angle measurement at
the pinion flange where the u-joint connect and record that angle. The two
angles need to cancel out to be in phase. That means if the front angle is
2 degrees down the rear needs to be 2 degrees up.
I on the other hand always set up my rearends to be 2 degrees down because
on acceleration with a leaf spring rearend the axle rotates up.
