Also, about the new X's. Only the Off-Road and the Manual Tranny X and S models have the D44 in the rear. Obviously the Off-Road does not need a rear locker and the number of Manual Tranny X and S models out there is pretty small. My guess they are building it for the Titan, which yes, does use the same D44 as the Xterra.

I want someone to come out with a locker for the front of the new X's.
