Differential Output Shaft Spline Counts?
What are the output shaft spline counts for the base diff, Z51, GS, Z06, ZR1?
And would this readily identify your carrier assembly as having the 27 or 30 spline input shaft design?

I did more forum reading tonight and I see no reference to the output shaft splines yet. Perhaps all C6 output shafts are the same? I did find where the hubs switched from 30 to 33 spline for 09-13.
This now also makes me wonder about half-shafts since the ones I have currently are from a 2012 Grand Sport. Are they proven stronger than C5? I know they are considered superior to the 05-08 shafts. I may run them for now and grab a pair of C5 shafts for later and just swap hubs back. This is all on a 2003 Z06 build.

I replaced the driver side half shaft a few weeks ago on a 2009 C6 Z06.
At the wheel bearing hub I counted 33 splines, at the differential side I counted 41 splines.
