1974 International Harvester 500 flatbed 1.5 ton Knapheide flatbed

Sold as the 1000 through 1500 D-series, the Light Line pickup was originally offered with four of International Harvester's own V8s, with displacements of 266, 304, 345 or 392 cubic inches. AMC's 232 ci inline-six engine had also been available, since the 1968 C-Series. Several different wheelbases (115, 119, 131, 132, 149, 156, or 164 inches) were also offered. The 119 inch version (as used for the Travelall) was only available as a bare chassis. In addition to the regular cab pickup, station wagon "Travelall" bodywork was also available, as was a four-door panel van version of the wagon and a four-door pickup called the "Travelette" (only on the 149 or 164 inch wheelbase).  The standard transmission was a three-speed manual with a column shift, but there were also four- and five-speed manuals and a three-speed automatics, with floor-mounted shifters optional. The automatic transmission was not available in heavier duty models such as the 1300D and the rare 1500D. Several models were also available as a cab on a bare frame for construction of stake-bed or other applications, some with an optional dual-wheel rear end, with available load ratings up to seven tons. These larger models were not popular, with most buyers opting instead for the Loadstar models.
