I an a bit late in thei thread. But If you havent bought a locker yet. You really should consider An Aussie locker. They are cheaper than either Lockrite or ez Loc and from everything I have heard the are better than both. I dont have personal experience with one because they dont make them for 10 bolts yet. But they do make them for D44 front and rear. I guy I wheel with now and then has one in his Jeep with D44 and loves it.
Here's some more info:

Here's a review of the Aussie from POR

I put this up because there has been little talk about Aussie lockers here. Even tho they look just like lockrite and EZ LoC. They are a new design the teeth are at better angles. and the springs/pins are a lot stronger They are made from a stronger alloy than lockrite.
