Ford F100 1966 Street Truck

This 1966 Ford F-100, the last of its body style before a full 1967 redesign, pairs Ford’s second-generation Twin I-Beam front suspension with a fully custom leather interior from Pro Auto Custom Interiors. See what made this final fourth-generation F-Series year mechanically significant.

A 1966 Ford F100 Street Truck that is just getting finished up with a very cool custom interior from Pro Auto Custom Interiors…The Boys out at Pro Auto just keep amazing me….Every interior they put out is cooler than the last…Check this one out!!

Ford built the 1966 F-100 as the last of its kind before a full redesign the following year, which makes it an odd choice for a show-quality street truck build, and also exactly why it works. Under the old sheet metal sits Ford‘s second year of the Twin I-Beam front suspension, a genuine engineering leap for a work truck of its era, paired here with a custom interior that has nothing whatsoever to do with hauling lumber. Pro Auto Custom Interiors built this cabin to look like it belongs in something far more expensive than a half-century-old pickup. What convinces someone to put show-car money into the interior of a truck that Ford originally built to be replaced within a year?

The Last Year Before Everything Changed

1966 marked the final model year of Ford‘s fourth-generation F-Series, with the completely redesigned fifth generation arriving for 1967, which means this truck represents the end of an era rather than the start of one, a detail that matters more to collectors than it did to the original buyers cross-shopping a new model year.

Twin I-Beams and What Made Them Different

1966 was the second year Ford offered its Twin I-Beam front suspension, a design that let each front wheel move independently over bumps instead of both riding on a single solid axle, a genuine ride-quality improvement over the truck’s competitors at the time and a feature Ford would keep using in F-Series trucks for decades afterward.

Engine Options Buyers Actually Chose

Ford offered the 1966 F-100 with a 240-cubic-inch inline-six as the base engine, a 300-cubic-inch six as a step up, or the optional 352-cubic-inch V8, and 1966 was also the first year buyers could add the newer 360 and 390-cubic-inch V8 options, giving the F-100 a genuinely wide spread of powertrains for a work truck.

Why Interior Work Like This Stands Out

Vintage trucks were built with utilitarian, vinyl-and-rubber interiors meant to survive a job site, which is exactly why a fully custom leather interior from a shop like Pro Auto Custom Interiors looks so dramatically different from anything Ford actually offered on the original order sheet.

The Street Truck Movement Behind Builds Like This

Custom street trucks have carved out their own corner of the hot rod hobby, treating vintage haulers like the F-100 as a blank canvas for modern paint, custom interiors, and upgraded drivetrains, the same treatment muscle car builders have given classic coupes for decades.

A Truck Worth More Than Its Original Sticker

Well-built F-100 street trucks from this final fourth-generation model year now regularly draw attention, and money, that would have seemed absurd to a 1966 buyer who saw the truck as simple transportation rather than a rolling showcase of custom craftsmanship.
