replacing luggage bay latches

I echo johnsonbert's recommendation for stainless steel hardware.

If I might make another suggestion: Once you are sure you have the hardware in the proper location and everything is aligned properly, I might recommend that you put some Loctite Purple (or possibly Loctite Blue) on the threads of the screws. I'd remove each nut, one at a time and put a dab of the Loctite on it so you don't cause anything to misalign. Then, with the Loctite on, snug each one up securely.

Or, if you're comfortable with a rivet gun, that's fine too.

A suggestion if your going to go the route of screws and nuts. if it were me, I look for the size you need in Stainless Steel. The big box lumber yards and Ace and True Value hardware stores have a variety of sizes with washers to go with them and at a reasonable price. Even plated screws will soon rust where the stainless will stay clean and rust free. Just my thoughts. Either method should work though. Hope this may help, happy trails Bert.

Either approach would be reasonable in my estimation, assuming there's sufficient access and clearance for the fasteners and tools needed. Pop rivet tools and pop rivets are affordable and easy to use (and nuts and screws are too, of course).
