Flywheel 2+2 280Z 280ZX 75-83 TurboNew stock replacement flywheel for Datsun 280Z and 280ZX 1975 1983, 2+2 only or Turbo (240mm). 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. 2+2 Turbo= 240mm clutch 2 seater= 225mm clutch
