A panel top assembly for a vehicle including a controlled guide roller management system and install/release mechanism. A pivotal portion, that is rotatable between a closed position and open position, is coupled to guide assemblies slidably connected to guide track assemblies. Each guide track assembly includes a forward isolator assembly that restricts undesired movement/rattling of a roller in a guide track. A rearward isolator assembly restricts undesired movement/rattling of the roller in each guide track, and selectively keeps the roller in the track when the panel top assembly is in a down/open position. The rearward isolator assembly also includes an isolator that selectively allows an opening in the track for releasing the guide assembly from the track to move the panel top assembly to an open/stowed position, and, reinstalling the guide assembly to the track.
