Its a spicer (Dana) M80 not sure what size it is, its an IRS. They are all the same size in the 04-06 GTO except the 04 has a smaller pinion flange then the 05-06 (LS2) cars which was required for the larger drive shaft. So all the internals are interchangeable. Theres only 1 company that makes gears for it and the tallest gear available is a 3.91. So the parts are limited for it. What exactly do you want to know about the diff?

The best thing to do with the diff is get 3.91 gears and a spring tuning kit.

The rear ends are ok for what they are. Some people get into the 10's with them while some break them in the 11's/12's. I've already had to have mine replaced. Either way they are very loud, they clunk and whine, but that is normal.
