You actually have a few options.
1. You can take your stock modular clutch, drill out the rivots, and either tap the flywheel to accept bolts, or use a nut on the PP side (use high grade hardened bolts though). There is just enough room between the Flywheel and the flexplate to use a shallow head hardened bolt. I have done it both ways for a few people before so I know it works. Then have the flywheel and pressure plate resurfaced and just slap a new disk in there.
There is a catch to this though. Some cars come with a Luk clutch from the factory and some come with a Sachs clutch. If you have a Sachs, you won't be able to make this work. If you have a Luk, you're in luck.
2. Buy another oem modular clutch
3. Buy a non modular clutch (used in the neon). That way the next time you can just resurface the PP/Flywheel and buy a new disk.
