Can you post a photo of what is broken and what you are looking for? Is this a US specification car, that is with the sealed beam headlight? This is the type with the thin (read that as fragile) piece that goes around the headlight and then has the turn signal/parking lights at the bottom?
If that is the case, this is a single piece unit. These are available from the usual sources. Buds, KK, Authentic Classics etc.
