New, high quality clutch plate from the German company that makes them for BMW, just a lot cheaper here.  All new construction, modern compound with sintered metal for better grab.  6.15mm thick.  Fits all airheads from 1970 to 9/80, when they changed the clutch and tranny input shaft.  I ship these fast via USPS Priority.   I have used these in my own restorations, and sold many of them to other builders for over 20 years--  not one hint of a complaint of quality or function.
