67 Dart Seat Medallion Questions

Good day,

I was hoping to get and couple questions answered if possible. I’m In the process of interior clean up, including redoing my seats and will be including the medallions. I was hoping to get a good picture of someones of what they appeared like from the factory. I’m not sure in the inner flat portion is supposed to be black, or supposed to be left chrome looking.

Thanks
Garret
