Align the hole in the distributor hold-down clamp over the hole in the intake manifold.
As the distributor is being installed, observe the rotor moving in a clockwise direction about 42 degrees.

IMPORTANT: If the rotor segment is not aligned with the number 1 mark, the driven gear teeth and the camshaft have meshed one or more teeth out of alignment. In order to correct this condition, remove the distributor and reinstall it.
