Query: I will not purchase heavy products on Amazon any more.

I purchased this to replace my current rails. I also bought a Curt Q20 5th wheel hitch.The box this arrived in was open and one end was totally torn off and repaired with packaging tape. It did not have any of the bolts, washers, or lock nuts in the package. It also did not have the brackets to mount to the frame. I went to the local hardware store and purchased grade 8 hardware and used existing brackets. I wish I would have only bought the rails and not the kit. I went to the local hardware store and purchased grade 8 hardware and used existing brackets.Very disappointed.
