This is a pic of the SE panel and trim,,,,
I am not sure what you guys are referring to as far as indent vs smooth ? ( do you mean the shape of the trim piece ? )

I think mine is fairly original, but who knows,,,
mine is a bit weird as well,,,,ie Western Sport special car,,,,that was built in hamtramack, not california,,,but shipped to california and sold new there.
It has the SE package, rim blow, wood grain dash, etc,,,

I will post a close up of my SE panel as well.

great thread and info
