Windshield for a 64 Dart question...

I need to replace the windshield in my 64 Dart convertible. I found a nice windshield locally from a 64 Barracuda, but need to know if it will fit. Also, I know they say that you need a different seal/gasket for the convertibles, but a member here told me he used the standard seal on his vert, and it worked perfectly. Any info on the windshield and/or the gasket would be greatly appreciated. THANKS!
