Liberty B4 Solid Mass flywheels.

[Nikopol]

So, the short of it is my clutch gave up the ghost halfway to work the other day (215K).

And of course the dreaded DMF leaves me replacing both the clutch and the flywheel.
I've been able to find the clutch no problem: Exedy FJK-7123HD
But I can't find a Single Mass Flywheel for the life of me.

What am I even looking for; an EJ20 flywheel or is it specific to the model/generation?
