My car had no sway bar, and therefore obviously no endlinks or anything, from the factory.
What I'm having trouble with is the install instructions show some really weird way to mix spacers and washers on the end of the end link that goes on the car itself. The beam it supposedly connects to is shaped like |_| and you're supposed to somehow stuff a bunch of spacers in between the two vertical parts, and poke a bolt through them from one side to the other. It's confusing the [censored] out of me, the spacers absolutely would not fit like that, and it seems oddly complicated.
