Limited slip, posi and detroit locker are all the same thing, just different names. Check this Link out for all the info, its really good

 

thanks

 

When you referred to gears 3:73s, those are in the rear end.

 

posi is GM's name for limited slip. A locker isn't limited slip, it's a locker--either locked(going straight) or unlocked (turning).
