The white mustang is most definately a 1965. It is also not a boss. It's a shelby GT-350 styled car with a ford racing 392 cubic inch crate motor...hense the GT-392
I live in Grand Rapids. On that part of the highway, where the sections of road connect, there is a jump in pavement. Most likely the main reason the truck flipped, along with speed of course. You should try hitting that on a motorcycle... nearly get airborne.
nice video compilation. My dad got a kick out of seeing his car on you tube.
