That adjuster is correct. In '57 they eliminated the one with the lock nut (two piece) and replaced it with one screw using interference threads instead of a lock nut. In '57 they also increased the rocker arm ratio to 1.54:1. Previous to '57 it was 1.44:1 I believe. Maybe 1.41 ? Looks like it's had some parts changed along the line.
