You might try contacting Suncoast Racecars in Florida for a '55/56 front end. They did make a body mold using a ’55 Mainline (no moulding holes) that I donated to the cause several years ago and they also borrowed some of my other parts to make other related molds for this same car. While I haven’t seen their front end, it was available but I can’t say if it’s one piece or multi-piece.
