The chromed plastic bows snap over the steel bows. They are extremely brittle and more often than not will crack. I've had some limited success using a thin wide chisel and a heat gun, carefully prying them off. Emphasis on "limited". The steel bows are held up by a sheet metal screw on each end. Panels lay up against the lips on the steel bows and the chrome plastic bows snap over the middle of the steel bow and hold the panel up.
