I have a 2010 Silverado with a 5.3L and 6spd and had some questions about the front differential regarding gear swaps.

I am about to put 4.56s on and was wondering if:

The spline count is 28 or 30.
The stock carrier can support a 4.56, and if not which one do I need.
Are they standard or reverse rotation?
