I made a cheap console for my Jeep by taking an old ammo box (the military kind, that helicopter ammo comes in) and painting it black. You can pick one of these up at an army surplus store. after painting it, you will want to drill four holes in the bottom of the box, and some corresponding holes in the floor of your jeep. After mounting it in the box in your ride, you can lock it the way that I did, by drilling two holes in the top front, behind where the closing mechanism is and inserting a U bolt. When you close the top and snap it shut the U bolt will stick out and you can insert a lock into it (hopefully the picture can explain a little better)
thats just great I am always interested in a good lock box as I do Jeep tours here in Belize and need this for our junk ,all I have to do is seal the holes in the bottom ,water proof .Thanks Captain Jack
