67 Belvedere window chrome piece part ID?

[Jax_1975_Dart]

Does anyone know what the chrome piece is called that connects with the driver’s window glass and fills in the gap between the back seat window glass and the front driver’s glass?

I’m missing this part and having trouble searching for it (mostly for lack of having a proper part name or part#) for it.

Attached is a photo of the passenger side one. My driver’s side is minus this chrome window accessory part.

Glass division trim. Just post a WTB with the same request and picture

In 67 there are 2 pieces, one on the rear window and one on front window.

Which one or both? Please be more specific.
