Can you remove this easily?

OK so though out my search for the "perfect mopar" or the "right one" I've noticed that alot of the Chargers I see for sale are the SE model. The reason I know its the SE is the fact it has the weird "opera windows". So i'm wondering can you remove them from a 1973 Dodge Charger SE? Heres a Pic to show you what I mean. Is it possible and low budget?
