It was the 03 update. The ones with the really nice headlights.

It is for this reason that when I was in the market for a D2 it had to be 03/04.

The very first D2's actually had the diff loch in the transfer case, there was just no lever in the cabin. You could climb underneath with a spanner and engage it.

Then LR, thinking that all was good, decided to remove it from the transfer case altogether, giving them two benefits, saving money and weight.
