LC3 to LC5 and Invincibles - 4wd differences?

[boma]

As per title.

I was wondering what or if there were any differences in specs between the UK spec Landcruisers of around 2006 - 2010, with regard to the 4WD systems.

All specs i find seem to relate to toys and interior.

Were there differen specs on diff locks, centre diffs, or any electronic gizmos for the 4WD between the versions, or was it reliant on spec check boxes at purchase time?

Thanks,

Dom
