In 1971 the 10-series light-duty trucks replaced the D-series. The styling was unchanged except for a new mesh grille, like that of the Scout, and revised shape and placement of side marker lights. There were no significant mechanical changes. In mid-1971 International made modifications to some engines to adapt them to new no-lead and low-lead fuels. The relatively low-compression V-304 and V-345 V8s needed few changes and maintained their power outputs. The 6-232 had to be detuned a little, dropping the hp rating to 135. Conversely, the big V-392 V8 was increased in power, to 253 gross hp and 236 net hp. In 1972 the light-duty series was given a new grille made of five thin horizontal bars split by a vertical center divider and extending around and beyond the headlights. The 1110 model got rear-wheel antilock brakes. In 1973 all engines were detuned for operation on unleaded gasoline and only net hp ratings were advertised. The new ratings were as follows: 6-258 6-cylinder - 113 hp; V-304 V8 - 137 hp; V-345 V8 - 144 hp (156 with dual exhaust); V-392 V8 - 179 hp (193 with dual exhaust). In mid-year the engine net hp ratings were reduced further to: 6-258 – 102; V304 – 126 (140 with dual exhaust); V345 – 132 (144 with dual exhaust); V392 – 168 (189 with dual exhaust).
