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.
Basic ignition tune-up kit for engines after 1980 and before Fuel injected. Approx 1980 thru 1989 that use the 59D distributor. The points typically have a distinctive blue plastic block in them. Kit includes points, condenser, rotor, plugs and wires.
With so many Classic Minis having been updated to later engines, it can be confusing knowing what to order. The most important thing to identify is whether the engine has an A+ block (from about the early 80s on), as the earlier block had a different distributor mounting and thus different distributor body requiring the earlier cap, rotor, and points set. All the Pre A+ engines in all the displacements (engine size) used the Lucas 25D Distributor. This can have either the old side-entry or conventional top-entry cap. It's quite easy to ID these, they have an arch-shaped opening in the side of the cap for the wire terminal. The later 45D and 59D Lucas points-distributors use the same cap and rotor, so that got a little easier. The electronic distributors of the late 80s and 90s use two Phillips screws to retain the cap and have their own unique rotor. See the chart above!
