I don't have any first hand experience with the 2nd gen D44, but any D44 full case locker, like ARB or Detroit should work. The main issue with those axles is re-gearing, but the locker should fit. You just have to take into account the thick Isuzu ring gear, and order the propper model (i.e. 3.73-)

The main issue people talk about with these axles is with lunch-box style lockers, that install into the factory carrier. But since you have an LSD, they should be an option as well.

HIH,
