Question on the trim above the window on a 69 SS

[69chevelless]

My 69 SS does not have the chrome above the window currently and I don't know if it was because of the ding dong painter that painted over it or was it even a standard option? A friend who's working on my car who's an Oldsmobile guy said it was an option for olds and not standard. I told him I thought it was standard on chevelles because I haven't seen one without it. So who's right, I need to know this cause I'm restoring my car.
BTW I'm talking about the roof rail trim.
