Looking at the sheet metal parts available online would seem to indicate that the 54 hood is different. I suggest you consider placing a request in the parts wanted forum. You could also call RPM Motorsports or Mongo's Garage to see if they have an used 1954 hood from a 3100 or 3600. Denny Graham has pics of the differences between a 1950 and a 1954 Hood in his "Album" . He is a great resource on these AD Trucks, you could send him a private message and he may be able to positively answer your question.
