The Fidanza flywheels are built to allow you to replace just the face rather than the entire unit.
VR-4 / Twin Turbo 5/6-speedNon-Turbo 5-speed (newer style 18-bolt face)Non-Turbo 5-speed (older style 20-bolt face)
NOTE: For the Non-Turbo FWD 3000GT/Stealth, the older flywheels (before about 2004 or so) used a 20-bolt face, and more recent ones (and current) use a 18-bolt face. If you have had your flywheel installed for several years, please check BEFORE ordering to ensure you get the correct face. You can either count with the flywheel out of the car, or from underneath remove the flywheel cover plate and mark a bolt and count as you turn the engine over one revolution.
