I stole Scotch740's idea for the contico tuff box in the rear of my TJ. I removed my rear seat completely and set the box forward
as much as possible. I needed more room in the back for Scuba Tanks. Here's the results
I just ordered one of the Contico boxes after seeing yours, and I found it at Zorotools for $55 shipped, awesome look, I plan on mine being at the back and bolted in, thanks for the great idea.
