Can the LSD mechanism from a factory LSD ep82 gearbox be fitted into a non-LSD ep82 gearbox? I thought about replacing the complete gearbox altogether but i have heard that the mountings are not the same for a factory LSD g/box and g/box without LSD. How true is this? and what is the difference between the factory LSD compared to other aftermarket LD like the TRD's & Quaiffe's?
