Yes, you need to replace them. You can get them and the nuts from the dealer -- I got mine there (they had to order, took something like two days) for something around $13. I have the part numbers at home that I can post later today when I get home. Or, if the damn search ever comes back online, you can search there -- I know there's a very informative thread on this subject out there.
Good luck, it's a KICK ASS kit! I love mine so far.
