I have a FX4 supercrew.

I want to add something like storage box for under rear seat. is there any company that make one for it? or homemade or just buy regular tool box size that will fit under rear seat?

I want to put something like strap tow rope, flares, flat tire kit repair, etc

Thanks!

found it....it is a factory ford storage that should fit under rear seat well.

Part # is 4L3Z-78115A00-AA
