    Flywheel question

    Does anyone know if the dimensions on a '69S flywheel are the same as a '67 911? I know the '69S pressure plate and disc are different, but will they work on a standard '67 flywheel?

    Thanks,

    John

    My understanding is that there was only one flywheel, and also used on the 914/6.

    Very early flywheels had different ring gear tooth pitch but I think this change had occured by engine number 901638.

    I am looking at flywheels from Patrick Motorsports for my spare engine #6392081. Does anyone know if their lightweight version is of good quality for street?

    Thanks for your comments Gents.
