This is how mine looked when I got it home from the dealership, FR repaired it but I don't have any pictures of how it looks after the factory repair, I'll try and post them. My original brackets were 3/16x2 steel straps that went up and over the I beams on both sides and not secured in any way. If they would have put a screw or weld to hold them in place I don't think I would have had this issue.

Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety.
