Personally I don't think I'd trust stainless for that application on a vehicle the way we use them. I Have had good luck with anti-sieze applied to most all chassis hardware to prevent corrosion. That or replace with a grease-able bolts I have those on my 40. Not sure if the material or size is changed for material removal? But I see your argument.
