After several PMs, Koso and I have finalized the policy regarding returns on this for our iS members. Here is the info short and sweet. If anyone has any questions regarding this, vendor or member, please PM me. My advice is to contact a member that has your year and model FX to verify fitment. Enjoy the bars...I've seen them in person and they are great.
1st gen group buy and 2nd gen non group buy purchases are both not eligible for a return after a member attempts to see if it fits because the policy states that if you "open the package" and "install/mount" it to see how well it fits, it voids a possibility for a return.
