The clearances were done to my specifications and the backlash was perfect. It took the master technician a full day to rebuild it and to get it right.
With the 4.083 gears the clearances and backlash must be better than factory specs or you will get a small amount of gear whine. Compare the factory specs on a frontier with 4.083 gears, 350Z with 3.5 gears and our 370Z's with 3.7 gears and look at the differences.
But since you trust your shop and seem to be happy with their work, I really don't see why you are complaining if your leaving out imortant info and are satisfied with what you have.

"until I broke it" You need 600h.p + wide low air pressure slicks & come out of a standing start at over 6,000 rpm to maybe break a well installed ring & pinion set. What I'm saying is obvious, so I'll leave it there.
