suburban trim between side windows

[mikesacs]

So, when I bought my suburban it had a box of parts in it including this side window trim. I'm guessing that this side trim fits between the windows, but I've searched a lot of burb pictures to see if this is painted the same color or contrasting color on a two tone and I haven't seen any pictures with this trim included. Was it a short lived trim piece? Any idea on what color it should be? FYI, this is a 1960.
