There are two 911S clutch/flywheel combos. The 1967 911S used a copper faced flywheel with a copper faced steel pressure plate and a standard friction disc. I think this was used for just one year or less since the copper facing wore quickly and caused problems. In 1969, the 911S used a steel faced aluminum pressure plate with a thin friction disc, and a standard flywheel. The 69S parts (PP & FD) must always be used as a pair. As the stock on these items is rapidly drying up, the prices are getting very high.
