Are all 8.8 gears the same?

Can I install a set of gears from an SN95 or New Edge in my '06 rearend? I need to change the pinion flange to the older style and want to know if it's a direct bolt-in or if the axles are different splines. Thanks in advance, guys!

the gears themselves are physically the same
