The hole tie rod assembly can be flipped making the inner tie rod install in the outer position and vice versa. That means that when you go buy either tie rod, it may not thread on because the threads are reversed. Buy a set so you have both and install them in the correct position based on part number. Examine the parts before leaving the store to confirm that you do indeed have t distinct parts. I buy tie rods locally for this reason.

edit: Note that "Febi" Bilstein is of a lesser quality than "Bilstein".
