Windshield and back glass chrome trim

I have a 1973 dart swinger and was wondering if I have to put the chrome trim back on once I install the windshield and back glass? I am not a big fan of all the chrome and did not know if it is absolutely necessary or not. If I do not need them will I be ok just using the gasket to seal the windshield and back glass? Or will I need something else along with the gasket? TIA
