Clutch linings are supplied undrilled. It is necessary to drill and counter bore these discs to attach them. If you wish, we would be happy to rivet them in place for you. Extra charges will be applied. This material works very well in this application. It is asbestos free but still retains very similar properties as the original material. It is recommended to also replace the cener plate, all springs, and all bearings at the time of renewing these linings.
