40-41 pickup headlight bezel question

[Sixseven]

I've seen two types of pickup headlight bezels. One has an integral parking lense frame where just the glass is inserted. Thats what I have on my pickup, it is also chromed and may not be correct for my truck. I have also seen headlight bezels with a detached frame for the parking lamp lens. I think the last one of those I saw was painted, or at least had no chrome on it. What is the difference where where these types properly used?
