Differential gears would only make noise when turning, but rarely go bad in normal use. It's possible you assembled something incorrectly on the pinion stack, or shift forks aren't properly adjusted. Reverse op sleeve cannot be set too near idler reverse teeth.
Synchros should be measured for installed outer diameters, especially when using Rauch & Spiegel parts. OE synchros are Goetze.

Wasn't aware that synchos required measuring whether R & S or OE?

Does the noise happen dependent on engine RPM or wheel RPM? This will give an idea what part of the gear box is involved. What makes it worse or better?
I would say that the noise is related more to engine RPM than wheel RPM.
Some additional observations. The noise is getting better??? It is most noticeable when decelerating at higher RPM and it definitely not a whine. I should mention that the transmission was rebuilt and installed with a brand new Sachs PP,Clutch and T/O bearing. Initially had a very hard time adjusting the clutch free play. Wondering if clutch was adjusted too tight? Is there a break in period for fingers on the PP? Also, absolutely no noise when taken out of gear and coasting at any speed.
