Bedside bolt sizes or kits?

[tantrumpipeline]

Was about to install the box on my truck and hit a major snag, none of the repro boxes contain anything to fasten it together. If anyone has size and quantity needed of each the bolts needed to do this with a stepper please post them, or if classic industries or brothers makes this I will order through them, these don't need to be coated or anything just for mock up, getting a little pumped on piecing it together is all thanks
