    Thank you Adam and Billy, so interesting to see why things changed. The large plate might deflect heat away from the (tight) driveshaft compartment. I wonder if the bulletins said anything about using that small plate, either the blank one or the one with the small tubes. The 1955 parts list uses the plate with the tubes. The 1957 parts list uses the blank plate? Would that prevent water from coming out the exhaust tube vent? Maybe Frank Robb or Gary have more info.
