Standard Ignition Distributor Rotor P/N:GB-359
Standard Motor Products
Keep high-voltage spark reaching each plug in firing order with the Standard Ignition Distributor Rotor GB-332. It is a direct-fit replacement for a wide range of classic European and specialty cars, including the 1981-1982 Mercedes-Benz 380SEL, 1981-1982 Mercedes-Benz 380SL and 1981 Mercedes-Benz 380SLC. The rotor turns with the distributor shaft beneath the cap and carries ignition voltage from the cap's center terminal to each outer terminal in turn.
Signs a distributor rotor may need replacing: engine misfire, hard starting, rough running, or a rotor tip that is burned, eroded or shows carbon tracking. These symptoms can have other causes, so diagnose the ignition system before replacing parts.
See the "Vehicles it fits" section for the full list of vehicles and engine-specific fitment.

This part cross-references / interchanges with the following part numbers:
What does a distributor rotor do?
It turns with the distributor shaft under the cap and passes high voltage from the cap's center terminal to each outer terminal in turn. This sends spark to the plugs in firing order.
What is the Standard Ignition GB-332 rotor made of?
It uses high-grade dielectric strength alkyd, which resists dirt sticking to help reduce carbon tracking. It also has solid brass segments for better conductivity.
Which vehicles does GB-332 fit?
Listed applications include the 1981-1982 Mercedes-Benz 380SEL, 1981-1982 Mercedes-Benz 380SL and 1981 Mercedes-Benz 380SLC. See the "Vehicles it fits" section for the full list and engine details.
What are signs my distributor rotor may need replacing?
Misfires, hard starting, rough running, or a burned, eroded or carbon-tracked rotor tip can be signs. These symptoms can have other causes, so diagnose the ignition system before replacing parts.
Should I replace the distributor cap at the same time?
The cap and rotor work as a pair, so they are often replaced together during ignition service. Inspect the cap's terminals for wear or carbon tracking before deciding.
