I made this grille swap 12 yrs ago. The Hood on the '54 does not need to be changed. I put the grille from '48-'53 in my '54. You can change out the fenders to make the job easy. I used the '54 fenders and sunk the '54 parking lights into the existing recesses in the fenders. Using the '54 fenders you have to do a bunch of sheet metal fabrication, such as squaring off the fender openings for the top corners of the grille, welding up a bunch of holes that were for the '54 grille mount. Then you need the bottom splash panel and braces from the '48-'53 grille. That ties everything on the nose together. I took me about a day and a 1/2 and a lot of beer. A week after I did this swap, there was a question in Old Cars Weekly about doing this swap. The response was "don't do it, too much work is involved". I should have sent them a photo of what I did and say "Don't say, don't do it - I did it!"
