A joint between a side rail and a cross member in a vehicle body and frame assembly provides for direct positive positioning of the side rails relative to the ends of the cross members to expedite the manufacturing process. The side rail is generally C-shaped in cross section, including a generally vertically extending web portion having upper and lower flange portions extending therefrom. The upper flange portion is formed having a longitudinally extending, generally U-shaped recess, while the lower flange portion is formed having a longitudinally, extending generally inverted U-shaped recess. The cross member includes an upper cross member having an end portion composed of a flange portion that terminates in a generally U-shaped protrusion. The flange portion of the upper cross member extends across the upper surface of the upper flange portion of the side rail, while the U-shaped protrusion is received in the U-shaped recess. The cross member further includes a lower cross member having an end portion composed of a flange portion that terminates in a longitudinally extending, generally inverted U-shaped protrusion. The flange portion of the lower cross member extends across the upper surface of the lower flange portion of the side rail, while the inverted U-shaped protrusion is received in the U-shaped recess. The side rail and the cross member are positively positioned relative to one another and can be formed using conventional roll forming techniques. If desired, a reinforcement member may be provided at the joint between either or both of the upper and lower cross members with the side rail.
