I doing a SAS on my 2003 S/C xterra and the guy doing it for me called me to ask me what axle do i have in the rear X right now. ARB has to axles for my X available with two different types of ARB locker, he needs to know what i have to be able to order it. I went under my X and couldnt really read the part number because of the rust. Was wondering if you guys can help me with this? thanks
