Windshield Seal for 64 Dodge Dart Convertible

Anyone have any information on locating the front windshield weatherstripping seal for a convertible?

Everyone carries one for a hardtop but I am not finding one for a convertible. Even Steele Rubber Products does not offer it.

Anyone know the difference between the hardtop and the convertible windshield and is their a possibility that a hardtop seal can be made to work?
