Ooops. Just noticed that you have a LSD in the back already. Hmm. Not sure how they compare to the locker. You may not see enough improvement to make it worth it if the LSD's work fairly well.

I can swing by Raleigh some weekend and you can drive mine in 2wd and see how the locker compares if you want...
