I wish I knew.

I thought all RX-7 input shafts were identical.

Bell housings, flywheels & clutch diameters vary.

Hmmm, thats strange that they would ask such a question. Every place that I have looked to buy a clutch package from has them sorted by vehicle model and aspiration.

Are you buying form a rotary friendly vendor or ACT directly?
