Correct, the easier route would be to just pull the 3rd member and swap in the LSD and keep the same gearing unless you plan to run taller tires 33”+. You will have to have someone reset your backlash though.

Great question. Ours and all 3.0L Mitsubishi’s trucks/SUV’s are 9”. All 3.5L’s are backed by 9.5” axles. And no the 3rd members are not interchangeable. I would verify that your axle came from a 3.0L.
