Easy. Use a Sharpie to mark each spark plug wire's position on the distributor. Then unplug the electrical connector at the base of the distributor and loosen the 2 cap screws. Remove the cap. Now pull off the old rotor. It should come off easily.



Install the new rotor, place the cap into position and install the 2 screws. Put the spark plug wires back in the exact same positions and you're good to go.
