I changed the differential gear oil and transmission fluid. This won't be a tutorial as there are dozens elsewhere, but please reply or PM if you have any DIY questions.
The jury seems to be out on how often to change, as there's no recommended change interval in the maintenance schedule and the interweb will suggest anything from anually to anniversaries, confirmations, and bar mitzvahs. Not knowing the age of the fluids, aving no service record of a change, and seeing as I've changed the other fluids I figured what the heck? The rear differential has been making a chatter/light clunk noise (but with no jering or vibration) on sharp turns, there is a TSB on switching to a gear oil with better friction modifier, and the transmission fluid was more beige/brown than red. Finally, I wanted synthetic for reasons as I have Redline in the rain car so I should have at least as good in the fun car!
The good stuff! I have Redline in the rain car because the cool kids on the G35 forum like it, and turns out some cool Corvette kids like Redline too. I was also able to get the gear oil locally at Lordco and the trans fluid on Amazon.
Car goes up!
Underneath the 'Vette, and the animals I've trapped, have become all of my friends, and I'm living off of grass, and the drippings from my transmission, it's okay to eat fish, 'cause they don't have any feelings... Something in the way, mmm-mmm.
I wonder if when designing the 2005s they knew the drain plug would be right under the leaf spring or they realised it later and then though they'd change it next year? Silly. I was able to get an alan key in there with a 10mm box wrench around it for leverage. Note: I had to loosen and tighten it with the suspension loaded as when unloaded it changed the angle on the leaf spring such that the alan wrench wouldn't fit!
I'm pleased to report everything went well. After driving a series of figure 8s the differential noise is gone. I also think the transmission shifts a little smoother.

I just let it drain, but a funnel is a good idea. It came down in a nice stream over the leaf spring about 1-5-2" wide then I just cleaned everything off. That old ceramic bowl was my grandpa's oil drain pan and it's a good size for draining oil filters. I had 2 plastic drain pans but one of them broke, I wanted 2 to let the trans and the diff drip for a while, so brought out the old bowl.
