Looks to me like that Chevelle went sideways in front of the oncoming car and got hit about directly at the rear wheel on the driver side knocking the frame right out from under the car and bending the frame and the body of the car all around the impact point of the rear axle... This damage has nothing to do with body mount bolts.. it's all about speed and velocity my friends.. I just wonder what the hell the dude driving the chevelle was doing to get into this...
