Not putting vinyl top back on - problems with trim?

My 74 Scamp originally had a vinyl roof. I've decided that I will NOT be replacing the vinyl roof. I see rear window gaskets "for vinyl roofs", but not for non-vinyl roof cars. Is there a difference? Am I going to have to find new bright work for around the rear window and the roof drip rails? Any other things I might have a problem with. I know I will have to grind off the little fittings around the bottom of the rear roof pillar where the narrow "chrome" strip went to separate the vinyl roof from the rest of the body. Any problems I'm not seeing?

Thanks,
