Brothers makes a billet center section for a 55-56 truck. A little body work to your 57 fenders and a 55 upper grille mounting panel and it's over. That's the way I went on my 57 because of the crazy price of a 57 grille. You can also check with JW Enterprises at customgrills.com, I think that he makes a tube insert for the 57 outer grille surround.Good luck
