I don't have a record of what the angles are on hand, but to be clear...
are all the components you are using stock?
If so, replace the rubber puck mountings on the front of the diff with
polyurethane ones and you are done here.
None of those angles need to be changed for a racing application; but the
bushings should be poly. All of that is fine for a fresh set of u-joints.
Spicer (best)  (or Japanese GMB? brand from TSImported Automotive ...fine
as well)
These are the last few u joints I have used and have served well.

A straight line drawn through the transmission output shaft should be =

the driveshaft is not parallel to these lines.  So if the rear of the =

Very right.

The flanges of gearbox and diff needs to be parallel or vibration will =
occur.

There is a god video about this:

Yes, great description. Greg. =20

For those of us with live axle cars you must consider the dynamic relative a=
ngle of the center carrier under load.  In higher hp applications the leaf s=
prings will wind up under acceleration and the angle will change.  In additi=
on to shortening the life of your u joint, it can lead to wheel hop issues. =
 Wheel hop can occur under hard braking from the same windup.  On my barracu=
da I stiffened the front spring segment to help limit axle windup.   On the C=
heetah there is no driveshaft to worry about... ;)
