Abstract: An apparatus and method are disclosed for modifying motor vehicle frames to provide for the installation of drive line components that are different, heavier or larger than the drive line components originally installed by the manufacturer of the vehicle or drive line components that were not originally present in the vehicle. Accessory hangers to provide support for those, different, heavier, larger or additional drive line components are attached to the frame without adversely affecting the structural integrity of the frame. The accessory hangers are easily removable to provide for the reinstallation of the original drive line components. The engine compartment is enlarged when necessary by providing spacers between the body of the vehicle and the frame to enlarge the height of the engine compartment.
