Steven, don't know how much this will help, as I don't have an example in front of me, but you should be able to cruise down to a local fastener vendor (commercial) with your tank and get something acceptable. There might be a huge minimum ($10:00 at my local, so I get stuff know I will need later). You might have to cut the screws to length, and/or color them black (sharpie?), but those little metric screws are not so oddball that you can't find a workable substitute. Of course, if you have to have the actual authentic factory part, that is something else, but often the replacement on something old is not "the original" anyway.
