Are 63 Fury and Belvedere doors interchangeable?

[65Fury440]

Would 63-64 Fury and 63-65 Belvedere all be the same?
What about Coronet and Polara?
Does a rounded rear bottom corner vs a squared off corner a good way to determine a 2 door vs 4 door?
Thanks!

63 B body doors are interchangeable between Dodge and Plymouth, the 63 is not interchangeable with the 64 and 65 due to different door hardware locations, the skins are interchangeable along all the 3 years, but not the whole door.
