Scout IIs were manufactured from April 1971 to 1980.
The design was frozen much earlier, with a version nearly identical to the production model shown to management in December 1967.

The Scout II is most identifiable by its different front grilles.
The 1971–1972 Scout IIs shared the same grille, three horizontal bars between the headlights and chrome rings around the headlights.
The 1973 Scout IIs had 14 vertical bars between the headlights, a split in the middle, seven bars on each side surrounded by chrome trim pieces and an "International" model plate low on the left side.
The 1974–75 Scout II grilles were the same as 1973, with the addition of a vertical bar trim overlay.
The 1975 had chrome and black, square trim rings around the headlights; 1976 had the same headlight trim rings as 1975, and a chrome center grille of 15 horizontal bars split into three sections was used in this year only.
The 1977–79 Scout IIs used the same grille between the same headlight bezels the new chrome grille had two large horizontal bars with three vertical support lines and the "International" nameplate moved up to the center of the grille on the left side.

In 1980, the final year of production for the Scout, the grille was a very distinctive design, available with black or silver, a one-piece grille with square headlights, made of ABS plastic.
Both grille color options had imprinted chrome trim around the headlights and an "International" name located on the left side.

Starting with late 1974 Scout IIs, disc and power brakes were standard features.
Early 1974 models had disc brakes as a rarely selected option.
 A three-speed A727 automatic made by Chrysler was optional.
