all you need to do is make a 5 minute call to any holden dealer spare parts dept. and give them you vin aslong as it is true and correct and they can look it up for you and then they can give you all the details you need.

Your car is a VT S2 Executive LS1(220kw), GU4 is V6SC/V8 performance diff with ratio 3.08:1(could be open or LSD, read tag on diff), M30 is 4L60E trans, not sure bout that 3BB in the model num, my calais has the same number too.
VT V8 executives were rare, and not many were made, mostly ordered, this makes them a "Collectable" car. The later in the genus was the SV8, which was basically a executive with LS1 engine and LSD diff, and they were quicker than same model SS !

weren't all LS1s delivered with an lsd?

VT2 LS1 execs aren't *THAT* rare... they pop up every so often on carsales but they don't generally last long
