Hugh,
On a new install like yours, when you don't have a reference you would have
4 possible variations to try if you should wind up with a vibration. First
rotate the diff attach points 180 d., drive it to see if it is better. Then
rotate the front trans/driveshaft flange180d., drive it and check. If not
better, then rotate the rear 180d (again) last. This will cover all possible
permutations with the least work. There are variations in the centering of
the output flanges and driveshafts, and by playing like this you can
sometimes 'tune' out a harmonic.
I wouldn't sweat it unless you get a 'bad vibe'.
Jim
