For the LS1 years:
GU2 = 2.73 gears and steel driveshaft
GU5 = 3.23 gears and aluminum driveshaft

The only issue I can think of is with the aluminum driveshafts on the 3.23 cars. They’re prone to making a “tink” type of noise when shifting into gear. I’ve had two GU5 LS1 cars and they both made this sound.
The steel driveshaft GU2 cars will not make that noise.

Mine doesn't have any such vibration. Been up to 120-130mph a couple times with this car, no vibration at all at any speed. I'm very happy with my "tink"-free steel shaft.
What speed does yours vibrate at? Are you sure it's not tire/wheel related?

i also get this horrible rattling from what feels like my console at about 50 mph exactly ONLY when my car is locked up in overdrive...but it seems to only happen when it rains, and not all the time. i don't know what the hell is up with that?

If you still have a stock mount, have you checked it for any cracks/damage?
Also, might not hurt to get your wheels/tires rebalanced if it's been a while.
Maybe your driveshaft needs to be rebalanced.
I would try all that stuff before spending the money for a new driveshaft. All I can tell you for sure is that my 2.73/steel shaft car doesn't have any of the issues you've described....

That's an odd one. Just an idea,.... are you using a stock trans mount, or a poly one? Poly will vibrate a lot.
