superbird front lower windshield moldings

[DoubleDlover]

So someone out here has tried the same thing. So im sure someone can help. Has anyone tried to use the front lower windshield moldings from a 4 door on their bird??? They look totaly the same. Ive looked and looked.... Compared.  Even put them on. I cant see a difference anywhere. BUT the book says the part number is different from 2 and 4 door..  What am i missing??? thanks.
