In September 1964 there was a change
in the design of the grille, the new grille featuring 13
horizontal bars accented by 9 vertical bars, the middle horizontal
bar and the 3rd and 7th veretical bars being slightly
larger than the rest.
The large round emblem was replaced with a rectangular shaped emblem, and the new P410 also featured large rubber bumper over-riders as can be seen on the picture at left.
