New stock replacement flywheel for Datsun 280Z and 280ZX 1975-1983, 2+2 only or Turbo. The 2+2 clutch cover is slightly larger so it has a different bolt pattern. This is a good upgarde from a 2-seater clutch as the 2+2 clutch is larger, but you will need a clutch disk and pressure plate for a 2+2 to work. All new part. If you ring gear is worn or the clutch surface, this is the part you need.
