If all else fails, you can just buy a 2010 Subaru rear net for $22.17 plus shipping. Two anchors come with it. Or, buy the 2010 side nets for $31.68 and get four anchors. Available from here: Utility and Convenience, SubaruGenuineParts.comDoes anyone have a source for the mushroom anchors that come with Subaru nets? Or, barring that, is there anyone out there with some extra anchors they'd be willing to sell?
Go to page 2 for the side nets. The 2010 nets will fit all Gen 4 Outbacks. Just a wider web than the ones advertised for 2011/2012. And, these nets have the clips to fit the hooks at the bottom and the loops to fit the mushroom anchors at the top.
