The only difference between the '47.1-54/55'1 hoods are how the holes are made for the front badge. Those holes are in the same spot. The difference is the earlier holes are recessed, whereas the '54/55.1 holes are flush. I believe that this difference does not interfere with attaching whatever year front badge you want to use on whatever year hood that you have.
Throughout the AD years, there are holes differing in number and location for the side badges.
I have a '49 truck with a '54 hood. It fits like a glove.
