The 47-53 splash apron won't work with the 54 bumper unless you flip the bumper over.
You may have to move your license plate also.

If you don't want to flip the bumper, you might consider just pulling the bumper in closer and adding a roll pan to clean up the look. I know I have seen it done and it looks good. Hopefully someone can add a photo that shows a roll pan/ bumper combo.
