OK, was missing two bolts have now bought 4 so 2 spare. All complete with the exception of 4 plastic covers over the top of the rails. But as the rails are really free, is a gift if you can resource or 3d print. £50 is really for the rails with locks. I would keep and put on the pop top, but with the extra height, may change ferry fees and have no idea of the strength of the pop top. So playing safe.
So save over £100, ideal for work van.
Collection only NR9 5AT west of Norwich city
