I just got my front and rear sway bars in the mail today. I picked them up from a buddy of mine, slightly used (show car) for cheap. All he sent me are the actual bars themselves. So I was just curious if anyone who has bought these brand new, I am missing anything? do I need special bolts or any misc. pieces that I did not receive with the bars? Also, is there an installation manual that I should have? Just want to get as much info together as possible before I get to installing them. Any info or help in regards to the install would be much appreciated.
