1977 New Yorker Brougham - is this a factory top ?

Not very familiar with Chrysler products but I like the lines of their full-bodied 70's New Yorkers, among others. I've viewed versions online but couldn't find one vinyl roof with this similar treatment. Was this factory or modified ? ( My ? concerns the copper colored version and I've included a pic of the common roof treatment of the silver New Yorker for comparison)

The trim on the front edge looks like an aftermarket installation from the 70's/80's to me.

Yes, looks that way to me also. I actually prefer the factory roof. It's much more distintive.
