Eunos - No Drive, Propshaft Spinning...Diff?

[Zeemax_Mini]

My brother was driving our 1990 Eunos 1.6 over the weekend when it suddenly lost drive. Looking underneath, when it's in gear with the clutch up, the propshaft is spinning and still connected to the diff. With the wheels in the air the rear right wheel spins (but can be stopped if you hold it) but the rear left has nothing at all (but turns by hand without much force). The right hand driveshaft looks like it's come away a bit from the diff, but that might be normal?

I'm assuming it's the diff but before I get into that has anyone else go any other ideas?!

Cheers,

Cheers guys.

The car gets thrashed as it's our shared track car, so it's fair enough that something has finally given up!

If it was a broken half shaft would it stop drive to the other side too? What's the easiest way to diagnose?

Thanks again!
