Abstract: An integral rear end bracket for facilitating the mounting and proper positioning of a prefabricated truck body onto a prefabricated truck chassis when the bracket is attached to the rear end of the chassis' longitudinal frame member. The bracket includes a plate member having a hook-like profile comprised of a stem portion and hook portion. The stem portion extends rearwardly of the chassis and the hook portion extends upwardly and rearwardly. The hook is so located that a forward portion of a usually C-shaped cross-member of the truck body contacts the hook when the body is at the proper position on the chassis and serves not only to locate the body but prevent forward movement thereof. The stem portion of the hook may be provided with preset holes which align with standard holes in the chassis frame for connection thereto. The stem portion may have further extending rearwardly therefrom a flange which properly locates and connects a bumper to the chassis.
