I’ve waited a long time to offer mechanical advise because I’m not a self proclaimed expert. I just know how to get the job done. Here’s what I found works. From underneath loosen the distributor adjustment hold down screw. Then from above get a very long #2 Phillips screw driver. Move the distributor advance or retard to access and loosen the 2 distributor cap screws. From underneath reach up and lift cap off with wires still attached and fish it over towards the battery. Change out what you want (plug wires, cap, rotor) then replace in the same fashion. Super easy to do. Don’t forget to set your ignition timing. Tighten screw from underneath. With the engine running at opp temp unplug the CTS. Then above you’ll need a timing light and I use a long rod with a hammer to lightly tap the distributor adv or retard till set at 12deg. Shut off engine and connect CTS. Also a good idea to reset your AIS at the same time. After making all adjustments disconnect and reconnect battery allows the computer to adjust. If your not sure how to reset you AIS I can walk you though it.
