Basic ignition tune-up kit for all engines from about 1974. The distributor should have a '45D' marked on it and the points have a distinctive red block. Kit includes points, rotor, condenser, plugs and wires.
The Haynes series of manuals are the best manuals for general maintenance as well as for major repairs and overhauls. Everything is covered from checking the oil to rebuilding the engine. No Mini owner should be without one.
