Spare CV - Storage

Hey guys, just trying to get ideas - guys who keep a spare CV axle in the truck, where are you keeping them? I had stuck mine in a Plano box to keep in the backseat or strapped to the bed, but I prefer a better option. Does anyone keep it under the backseat?

 

There used to be a guy that made molle panels for the backseats. I wonder if something like this would work for ya? Just strapped down and more refined of course. Im doing the plao case as well. https://www.tacomaworld.com/threads/my-solution-to-behind-the-seat-storage-with-molle-panel.474253/

 

Wonder if u could wrap that bitch in a plastic bag and tuck it inside a frame rail somewhere.
