Can someone please tell me what the diff ratio is in an AU2 4.0L 4spd.Is it 3.08??? I was considering a change to either 3.45 or 3.7.Also what is the difference between fitting an LSD and a Hydratrack centre???

AU2 (non XR) auto should be 3.08. If you go to hydratrack you will have to change the axles as well as the hemisphere. Also hydratrack seem to have died a quiet death, probably due to their scary unpredictability once they have a few kays up.
