Am just curious. I removed the rear seat for good last weekend (much better). I noticed that there was another set of hooks on the floor under the seat like the ones in the rear that the vertical net attaches to. Is there a hold down net to use for flat hold down using these 4 hooks available? The vertical one isn't a good fit. Am sure that there is one for another make of SUV that has the correct dimension, just not sure which one, any help
