Hi guys, just got back from picking up some parts from a guy wrecking a 2nd gen and we got talking about different upgrades
He had one there with 5 lug front and rear.
Diff and hubs from a Mitsubishi L300 van, which shares the same chassis as the l200. He said the diffs were not as good as the L200 but the diesel vans had slightly stronger axles.

I guess these were not produced or sold in North America, but I remembered a few threads on here asking about 5 stud conversions. Quite a few l300 vans around over here, my neighbour even has one. Perhaps there's a market to ship a container of parts stateside
