If the fluorescent lamp holders are broken, it would be best to replace the light fixture instead of trying to find holders for the old ones. You probably won't be able to find the replacement parts and would likely end up having to order them from the factory.
If you are trying to remove broken or burnt out fluorescent lights, just twist the bulbs around to where the slot is and then pull them out.
