hardtop v sedan windshield dimensions?

does anyone know the difference between a hardtop windshield vs a sedan windshield? specifically the metal trim ?

I Have a bottom trim piece from a 68-69 dart hard top-- it is the same length as the sedan piece I have-- I do not have the set for the hardtop to compare. I know sedans take different windshields than hdtp.

is it height difference?
does anyone have a correct answer? thanks Lawrence
