Cutting a TracRac to fit a short bed

I have a Nissan Titan short bed.  I'm looking at cutting a used set of TracRacs to fit my truck.  Has anyone done this or seen it done?

From what I can see the vertical posts bolt to the horizontal and have a track that allows for side to side movement. It looks like you should be able to make it work. Worst case just make sure you know someone with a tig welder and you can chop/cut/ modify to make anything work.
