When installing new spark plug wires, it is common practice to install a new distributor cap and rotor as well. The air cleaner assembly might need to be removed in order to access the distributor cap. Loosen all the mounting screws on the distributor cap and on some models it is held in place by clips that can be released by pressing down on them with a screwdriver and turning them about 1/2-turn or just one quarter of a turn for others. You can then lift up on the cap and remove it from the distributor while still leaving the wires attached. The rotor, which is located at the end of the distributor shaft, should be examined for signs of cracks, carbon tracks, corrosion or wear. Upon removal of the old rotor from its shaft, it can be replaced with a new one. It is indexed to fit only one way on its shaft.

While checking the inside of this part, closely examine terminals for presence of excessive corrosion or damage. Replace if uncertain as to whether cap is still good.
