Paul,
IF you take the Cargo Net Part Number to a Ford Parts Dealer and ask him for just the Mounting Nuts Package, they can look them up in the Bill OF Materials for the Cargo Net and order them for you.
I broke one of mine, and had to reorder them this way. You can't find the number any other way since the net is not a STOCK item with the car.
The Cargo Net is worth every penney though. it is NOT a single net, it is more like an elastic envelope that is suspended between two posts. You can put things IN IT, not just between the trunk lid and the net.
Pete...
