I'm gonna talk to both Jim Tucker and Totally Stainless about their SS fasteners to see what they actually market. The body bolts/screws won't require much in the way of mechanical properties, so it is just a matter of finding restoration quality fasteners. Langdon sells an engine accessory fastener pack that I definitely need more info on. Don't need any generators, starters, distributors, etc. falling off in fatigue. At least the forum gave me some contacts and can sort through the offerings to find the fastener mechanical properties I need. for each application.
