Installing a Composite Wood Truck Bed in a 1970 C-20

I wanted the look of a wood bed, bt not all of the work taking care of it. I used Composite deck material and all stainless hardware. I also used Rivnuts instead of carriage bolts to make it easier to replace any damaged boards.
Here is a list of materials and special tools needed.
