Set of 10 zinc plated top pulley shims to fit the top pulley on aircooled VW engines There should always be 10 shims on a top pulley so you can adjust the tension of the drive belt by adding or removing shims from between the 2 pulley halves. The spare shims should be put behind the thrust washer for future adjustment. The top pulley, Woodruff key, Drive belts and Thrust washer/Nut are also available from the Wolfsburg restos ebay shop.
