I am installing a lift on my used Jeep I just purchased. The PO removed the bump stops and cups so I need the stock set ups. It seems from what I read that the ZJ fronts will fit the TJ rear. I also read conflicting opinions the ZJ will fit the front and that they are different. So what is the verdict on the bump stop cups? ZJs will fit all around or no? If not what cups do I need for the front of the TJ?
