Calculating the angle is pretty simple but you need an angle finder. This is
a 360` wheel & pointer mounted on a magnetic base. They are available at
some parts houses & also lumber yards & home centers. The pointer always
points straight down, & the scale shows the relative angle to whatever the
base is against. Put the base against the end of the transmission and at the
end of the diff housing or flange. The difference between the 2 angles
ideally will be 2-5 degrees. You need some angle to rotate the bearings in
the U-joints, but not so much as to cause undue rotation & premature U-joint
failure. This in not rocket science, but will give very accurate measure
using a $10.00 tool.
Search the archives for many more references. Be sure to have the drive
shaft balanced.

Subject: driveshaft phasing
So far, I have only 'eyeballed' my driveshaft angles, and before I have the
driveshaft made I'd like to read from others (who have their cars completed
and
successfully driven high speeds) about just how precisely they set up the
interference angles on their driveshafts - and how they did it. I
understand the
intent of the setup but I dont have any actual, hands on experience. I
dont
want to try for precision that isnt needed but I dont want to be cavalier,
either. I have a solid axle that can be shimmed and I'd prefer not to
re-engineer my motor mounts and transmisssion mounts ... Any stories will
be
appreciated.
