Hey.... Those look GREAT!
Look for hardware at either a local ACE hardware store or, as Ray mentioned, Marine hardware would be a good choice, too, and you've got... what? Three West Marine stores near Pensacola?
Look for counter sunk, "Oval Head" (sometimes called 'dress') SS machine screws. Get some stainless Nylok nuts and SS washers for the underside of the body, too. It's always fun spending money at West Marine. 😖
Take along a hinge to match up the hardware size (mine were 6mm, IIRC, but your mileage may vary) as well as see how the different screw head designs (flat, domed, etc) look in the hinge.
