1966 Barracuda Lower Glass Moulding Rubber Gasket

Hi there. Looking for the half moon rubber piece that goes in between the back glass and circular part of the lower rear glass trim moulding. The part with the fish in it. On earlier 64-65 this would be behind the circle with the valiant "V" in it. Mine didnt survive removal and I know they do not make this anywhere. If anyone has a usable one please let me know. Also if anyone has fabricated one, please share what you did. It is def possible to make one with a piece of rubber I think but I figured I would ask first.
