I've a complete 9" rear end from a Montero Sport, gaining you disc brakes as well as essentially being bolt on, simply needs a new leaf:

Track down and bolt in any 9" diff/carrier you want from a 3.0/V6 Montero/Montero Sport/D50/MM on car-part.com; the 3.5/V6 Montero/Montero Sports had 9.5" rear ends and won't swap, fyi.

This vin decoder should help determine which donor trucks have open, LSD, and factory locker rear diffs:

It doesn't look like you're too far from the border so freight likely wouldn't be too steep via fastenal, etc... https://www.fastenal.com/en/22/blue-...rty-logistics)
