Free Tool Box for bed

Thanks for the input all. Lid opens and closes perfectly, and tested before I drilled. Held in place with clamps first to test fit. Box is centered between the bed rails, and this box will not be getting any major weight put in it. Basically storage for some of my jackets and extra uniform stuff at UPS that were just laying in my backseat, which made it a bit of a pain when I had to have the kids ride in the backseat. Nice having extra jackets/thermals on hand when they’re needed.
