How to tell if your trans has a Quaife?

[Jermoturbo]

I'm wondering whats the easiest way to tell if a trans has a Quaife installed without taking anything apart? I'm looking into a FWD DSM trans that supposedly has a Quaife in it, and want to be sure it has one and not some type of "clutch" diff locker.

If you can spin one cv shaft and the other one spins the same direction and same speed then you have an LSD FWD trans. If it spins the opposite direction then it's not an LSD.
