The re-enforcement plate under the front cross member 51717028433 has 3 holes on its front edge and 3 on rear edge. The front edge holes are used to fasten the plastic engine undertray. The three at the rear look like they should hold an undertray under the gearbox, but mine doesn't have one. Should it?
