Ignition rotor button to be used on Lucas 45D distributor and 59D distributors originally fitted with points.
Many ignition failures have been attributed to inexpensive rotors that are built down to a cost at the sacrifice of quality. These fit better than others currently available, and all of the common causes of failure have been eliminated. There is no rivet to come loose, they are red so there is no carbon to cause tracking, and the rotor-to-shaft fit is correct. Now in blue.
