Change it. Don't be a dumb.
There are none.
Drill out the rivets
The ignition module is located in the distributor under the rotor, it plugs in.
To change the distributor cap and rotor on a 1987 Corvette L98 motor, first disconnect the negative battery terminal to avoid any electrical issues. Remove the distributor cap by unscrewing the retaining screws and carefully lifting it off, noting the position of the wires. Next, pull off the old rotor, which is typically secured by a single screw or may just lift off. Install the new rotor by securing it in place, then attach the new distributor cap, reconnect the wires according to their original locations, and finally reconnect the negative battery terminal.
From the factory, Corvette rotors were riveted to either the front hub assembly or the rear spindle. To remove the rotors from your Corvette, drill out the rivets, removing the head of the pressed in rivet and then pull the rotor off. The rivets, still remaining in the hub assembly or spindle can then be cut or driven out with a hammer. To install the new rotor, the rivets DO NOT need to be replaced. The Chevrolet Corvette service manual recommends simply using the lug nuts of the wheel to hold the rotor in place. From all of us at Zip-Corvette.com
It is quite common for rotors to be stuck in place. Tap on the back of the rotor with a hammer, until the rotor is loose.

The cap should only be 2 screws. You depress, turn 1/4 then they pop off. The rotor is inside & should be a screw or something in the center attaching to shaft.Make sure you know which terminal is #1 & have firing order before you pull wires.
