so i was looking into a rear locker for my trooper, the only one available was designed for the front 10 bolt, which has some minor differences. my questions unfold...is anyone running a locker in their rear 10 bolt? any issues? i am tempted to upgrade to the 12 bolt, disc brakes! and more locker options...but would that mean i need to change the gears in my front 8 bolt, since the new rear would likely be 4.55's not the 4.10's im pretty sure came with the turbo diesel rear 10 bolt? and did any of the second gen troopers come factory with a locker? searching online, some of the used car part places list the 88' options as locking, or non-locking, adding further mystery. hmmm, so should i stick with the 10 bolt, get the aussie locker and be done? or upgrade for better brakes,durability, and more gear/locker options?
