I've searched. I swear.

I've discovered that the offroad uses a 44 rear axle. That means I should be able to go to an air locker in the back (if I ever have to replace the existing one).

But what about the front diff? Is it the same differential that's found in the <'04? If so, i'll go on down to the happy little nissan dealer and plunk down the cash...otherwise, I guess I have to wait on the FJ
