The end links connect the swaybar with the suspension (I think the struts). They are around 6-9 inches long. They are easy to replace. My mechanic charged one hour to do both. I don't know if the rear bar has these- I think not. I lived with the rattling for four years. It was most apparent when driving over washboard or broken pavement with the swaybar unloaded (i.e. going straight). When going around curves the problem was not as noticeable because the swaybar load prevented the rattling. If you put the car on a lift you will be able to tell very quickly.
