Poor packing. the parts fell out as the postman handed them to me, one side of box split end to end,the other split half way. The rail ends were far from ready to fit. the bends must have been bent with a mallet, with fish tail ends. The end bungs could never fit flat ends.One rail was 50 mm too short, it was replaced with one 25 mm too long.The holes were too small and put in at random, what a dogs dinner.It took me,a skilled toolmaker, eight hrs. to fit. The side curtains were ok but tailgate were only 25 mm longer than side ones. This is my first bad review ever. The rails need inspection before sent. Ian Henderson 12 Oct 2017
