A selectable/ lunchbox locker, sure. But I think you would have to be somewhat nice to it with 33's, but you only have a 2.3L also, so that cuts back on the risk of breaking stuff alittle.
What ever you do, DO NOT weld the front. My Ranger has a tighter turning radius that Derek's LJ. I'm open front and rear, and he's welded front and rear.
A ratcheting locker is only slightly better than welding it.
I think you would be better off getting a locker for the rear, but that is just my opinion. Limited slips are just that, they only LIMIT the slip and are not super effective on the trail in my opinion.
