- Before mounting distributor, take off cap, remove rotor and dust cover.

- Assemble distributor to housing, meshing the gears while retaining the terminal wire or stud in an approximate 12 o'clock position.
- Mount distributor clamp to drive housing but do not tighten screw.
- Adjust breaker point gap to 0.020 inch maximum opening.
