You would need to cut the window frame off the sedan and weld it to the ht door and use the glass from the sedan. I know that hardtop door panels are a different size than the sedan panels so the door may also be a different length.
With the exact same roof, hood, fenders, dash, between the 2 dr and 4 dr sedans I can't imagine 1966 sedans not being the same windshield.
btw can we see a picture of your Fury?
