Abstract: A vehicle body includes an underbody having one or more underbody bolting flanges attached thereto, with each underbody bolting flange being adapted for bolted attachment to a mating bodyside bolting flange. Left and right bodyside subassemblies are joined to the underbody, with each bodyside including a supplemental bodyside support structure having attached thereto one or more bodyside bolting flanges, with each bodyside bolting flange being adapted for bolted attachment to one of the underbody bolting flanges after the bodyside subassemblies are otherwise joined to the underbody. The underbody bolting flanges are attached to supplemental cross members that are attached to and extend across the underbody.
