Most likely the harmonic balancer and water pump must be removed so you can get to the Opti-Spark unit. When replacing the cap and rotor assembly be sure to reconnect the vacuum hoses to the cap. They're important. They keep fresh air flowing through the distributor cap that prevents corrosion under the cap. HTH. -Jim

Oh, how long does it take for a non mechanic to do you think?

With a harmonic balancer puller, maybe 3 or 4 hours. Figure on a Saturday afternoon to do it. HTH. -Jim
