My 73 Bonneville has points type ignition. The later years had electronic ignition distributors, which had .045 or more gap. If you're engine is points type, the gap is .035.
There are no points it has electronic ignition.
The dwell for the points should be 30 degrees. The spark plug gap should be .040".
If you set the points at 30 degrees you will be fine.
