I think the problem may be with terminology. There is what I would usually call a flywheel on the 97 RS, but with a modular clutch, the "flywheel" is just a thin disc with teeth for the starter to engage. There is no machinable surface. This must be what Ronin referred to as a flexplate. Also, as Ronin said, the flywheel AZ listed was nothing like the stock unit. It was a "real" flywheel, thick enough to be resurfaced when necessary and capable of supporting a component clutch set. So, mystery solved. No flywheel included, but none necessary.
