Outer Limits 4x4 Board

Hey guys, so I cracked the rear diff housing on my NH Pajero on the weekend and am now looking around for a rear diff assembly complete with factory rear locker. The issue I now have is I have found a rear assembly for a good price minus the diff centre and have also locked a 3.0L factory locked diff centre. The question is will this work, I hear that in the 3.5 the axles are longer for the LSD over the locker is this true of the 3.0 as well?

Gotta make the call asap so let me know if you do!
