I believe that was the same net I bought that was supposed to fit my Fiesta. Didn't, as you can see from this pic I took. Like the Focus it just had those square shape hooks. The cargo net had to be stretched to try to connect to them and it pretty much made the net unusable.That part number comes up as the envelope style net. An example can be found here:
I bought a universal like this for my hatch back. i posted pics in the learn things about your focus thread a while back. there's 4 mounting hooks under the carpet for it.If it's like this one, it's probably the one for the sedan.
