I have been having difficulty identifying the correct headliner bows for my 67 SS Nova. I have a few different used sets from Novas but think they are for a sedan as the three rear bows are too short for my SS car. I think what I have are bows from a sedan car. Does anyone know if the three rear bows on a SS car are longer that those in a sedan as the ones I have are too short. Any help is appreciated.
