Clutch linings to be riveted on to clutch plate. Sold in pairs. Linings  require drilling, counter boring, and riveting onto the original clutch plate. If you are not able to rivet them on, send the clutch plate to us, and we would be happy to do so. The lining material has very similar characteristics to the original. It is asbestos free. We have used this material in many Pre-War Rolls-Royce and Bentley motorcars and find it to be the best option.
