Very right.

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

There is a god video about this:

A straight line drawn through the transmission output shaft should be =
close to parallel to a line through the diff pinion shaft.  It is OK if =
the driveshaft is not parallel to these lines.  So if the rear of the =
trans is tilted down 6.5 degrees then lets say the driveshaft is level, =
the front U-joint operating at a 6.5 deg angle will cause the driveshaft =
to speed up and slow down as it rotates.  If the nose of the diff is =
tilted up at the same 6.5 deg, these velocity oscillations will be =
cancelled out by the rear U-joint and the diff pinion will rotate =
smoothly.

=20

When you say the diff is tilted downward at 5.5 degrees do you mean that =
the nose is pointed down?  This would be a bad situation as the =
oscillations of the driveshaft would be exaggerated rather than =
cancelled by the rear U-joint and you would have nasty vibration.  =
Hopefully your diff nose is pointed upward 5.5 deg.  This would place =
the imaginary lines within 1 degree of parallel and close enough for =
smooth operation.

Need a bit of advice regarding driveshaft angles.  The rear transmission =
flange is tilted downward 6 1/2 degrees.  The diff is tilted downward at =
5 1/2 degrees.  The difference is 12 degrees.  Is this too much for a =
universal joint setup to manage?  We've considered raising the front of =
the diff, but then the spring will be twisted and we don't know how this =
will affect the rear suspension. Any help is appreciated.
