So I have 3 1970 Darts. All came originally with vinyl tops (Dodge had packages and deals that included vinyl roofs that year). I have removed the vinyl roof on 2 of the cars and the third one still has its original factory vinyl on it. I left the vinyl trim on the purple car because one day I might want to paint the top a contrasting factory color (an odd but available option that was overshadowed by the cheap vinyl roof thing). I put the vinyl top drip rail back on both the cars with no vinyl and had to squeeze it shut a very little bit to have it snap firmly in place.
