High quality aluminium or paper cylinder base shims available in a variety of thicknesses to allow for the fine adjustment of your Lister CS's bump clearance.
These aluminium shims should ideally be inter spaced between gaskets of the same type made from paper which are supplied in our full gasket sets or loose from this listing. The aluminium shims can be used without paper gaskets in between if every layer is bonded together with a jointing compound such as Heldite.
