Uh. Pretty sure 200 (and 180) mm refers to the clutch disc and pressure plate sizes that fit. The flywheels are recessed for those elements and the tooth-to-tooth diameter is quite a bit larger—and pretty standardized (?) which is why you can hang a Type 1 or a Type 4 or any early Porsche pushrod (616) or 4-cam (547 or 692) on any early VW air-cooled transaxle.
