I have mounted a 54 hood on a 49 (all Chevrolet). It fit absolutely perfectly with the 54 hood catch and the 49 hood latch. Therefore, I cannot imagine any problems putting 47-53 hood on a 54 truck. The 47-53 hood front emblem holes (four of them) are recessed. I believe that the 54 emblem will still work.
The 49 hood will have extra holes on the sides for the 3100 emblems below the CHEVROLET emblems.
