The basic design features of the Getrag rear differential have changed, and they should be noted.First, the actual internal structure of the housing is redesigned to produce less flex and improved sealing. This heavier casting means more rigidity, and less side cover flex to reduce the leakage prone to the c5 axle.
However, they cannot be interchanged, as is seen in the picture below. This is the drivers side of the axle.
The housing now uses 2 rear mount locations to fastening to the rear subframe. This particular 'Four Point' suspension system for the driveline reduces vibration and twist to the driveline. It was used on XLR first, with excellent results.
Output shafts are now all strengthened in a different fashion to reduce breakage with drag strip usage.
Clutches and the tension washers have been changed also, for increased reliability.

I'm talking the ring and pinion gears . Not the whole diff.

Well, I guess if you have the gears sitting around, you either have the knowledge and tools to do it properly, or have a shop who can do it. Either way, it sounds like the case and shafts are the big upgrade, so yes.
