The plastic shroud on my license plate light got brittle and broke at the back end, where the screw would hold it in place. Does anyone know if this shroud is available as a separate piece? I don't want to replace the entire light and license bracket if I don't have to. I looked at some on Amazon and they are the whole thing, and I can't tell if the shroud separates from the rest of the parts on those or if their shroud will fit. TIA.
