5. Using a long screw driver, align the oil pump drive shaft to the drive tab of the distributor.
6. Guide the distributor in place, ensuring that the spark plug towers are perpendicular to the centerline of engine.
7. Once the distributor is fully seated, the rotor segment should be aligned with the pointer cast into the distributor base. This pointer will have a 6 or
8 cast into it, indicating that the distributor is to be used on a 6 or 8 cylinder engine. If the rotor segment does not come within a few degrees of the
pointer, the gear mesh between the distributor and the camshaft may be off a tooth or more. If this is the case, repeat the procedure again in order
to achieve proper alignment.
