I'm working on my 55.1 grille. All components require repair, most notably those fat "middle" bars that bolt to the side of the nose piece. The l.s. middle bar didn't look like it fit right and after awhile I realized it is different! I'm guessing it came off a larger truck. But I'm stuck with it and either have to repair it and use it as is, modify it to look like original (a lot of work) or find a suitable replacement. I'm thinking these grille parts are rare. Any ideas?
