Nismo Twin Plate Plate Orientation

[Danox]

I have a Nismo Twin Plate for my R34 that too many people have handled, and the orientation of the clutch discs is lost. Each disc is the same, but both have the tabs on the center of the wheel leaning towards one side of the disc. I can arrange the clutch four different ways, with the tabs towards the center hub (larger gap between plates) or facing away from the center hub (smaller gap between plates). We put it together once, and the plate closest to us (standing where the gearbox was) had worked loose and it's tabs were somehow not in the hub. After the 2nd disassembly, we started to question the assembly orientation.

Can anyone tell me which way is correct?
