The best is to use the new ones but look at the old ones to determine how they go on. It can't be described without pictures.
They are spring metal and will lose some of their tension after being hot many times. Their purpose is to prevent rattles and often to provide a replaceable wear surface to prevent grooves from wearing in the mounting knuckle. Use the new ones if they're provided.
