REMOVEDistributor Assembly:
1. Place the distributor in a suitable holding device, if removed from the engine.
2. Remove the cap.
3. Remove the rotor.

4. Install the snap ring.
5. Position the wiring harness in the slot in the distributor housing. Install the two pickup coil plate screws and tighten.
