For me, it was this story that made is something special.
1965 - In 1965, the Twin I-Beam front suspension was introduced with coil springs. It was offered only on light-duty two-wheel-drive F-Series pickup trucks, giving them a softer ride and better handling characteristics.
The 1965 and 1966 trucks have a "TWIN I-BEAM" emblem on the front fender. Source: http://www.blueovaltrucks.com/resources/f-series_history.htm
