What models of the Sport got the 3.5?
The 99 Limited has rear leafs with the 3.5l and very commonly a locker, I have yet to see a 99 Limited without the locker.
2WD or 4x4?
4x4 not sure it was an option on 2wds.
don't see the 3.5l 4x4 as an option on Car-Part for '99 Sports - odd
Wonder what the mileage is.
Mitsubishi Montero 4x4, clean title, 7 seater - $2500

If it's really as clean as the pictures show it, that one would be worth the re-power, should it be needed. Sadly, its just too far away (for me)
