Briefly, here's the process.
Assemble the T-Anchors

Locate the panel fasteners on the top and bottom on each side, and remove. I ended up going to Harbor Freight and buying a cheap removal tool. The top ones were a bit of a bitch. The bottom ones the plastic sill were much easier to remove. Screw the T-Anchors in nice and tight. As I said, I had to use a pair of pliers on the tops ones.



Attach the cargo net and you're done
