For Hitachi D4A Distributor (points) distributors, D4F (remote ignitor) and D4K (matchbox) distributors. All 1974-1982 model B210, B310 and N10 (310/Pulsar) use the same vacuum advance modules. Advance varies slightly by year and model (see Spark Curve). Some are advance/retard units. See Datsun Factory Service Manual for the specs. Original B110 distributors use a different shape module.

ANY modules fit and work "OK", but none are correct for performance -- they are all emission related. The curve can be adjusted. Just remember it has zero effect on full-throttle acceleration (vacuum advance only works at part throttle).

These two screws fasten the Vacuum Advance module to D4K. Remove screws and pull module out

Dot is color code for the advance curve. You can peel the sticker off, dig out the clay, and adjust the total advance. The internal spring controls the steepness of the curve.

Vacuum Advance rubber diaphragm gets old and brittle from age, cracks, then won't hold vacuum. Replace the entire unit (unless you know of a source for new rubber?)
