As we all know samurais are a little short on stowage space. to organize the back of mine a little i found an old ammo box approx 30"x10"x10", i'm not sure what kind of shell it held, something like mortars or something. I removed the back seat and seat belts and the clasp so there was no evidence of a back seat just some bolts and a few holes. i centered the box and drilled two 3/8" holes approx 4.5" from the inside of the box but you can use your own measurements. it fits perfectly between the wheel wells and holds all my tools and recovery gear.
