On each side of each of the factory roof-rack cross-bars are two bolts that seem to hold the bar portion of the cross-bar to the attachment point that slides on the rail.

On my front right side, two of those bolts have disappeared. I don't know if someone took them out or if they just back themselves out. Now there's a rattle from rack and I don't have a lot of confidence in attaching my cargo box to it.

I went to the dealer and they told that I have to order a whole new set of cross-bars. I thanked them for their assistance and left.

Does anyone know if there is a part number for these bolts or what size they are? Pics attached in case my description wasn't clear.

Thanks!
