Welcome John. Someone posted recently that stainless are about the same $$$ as chrome, look nice and shiny, are easier to care for--e.g. buff out scratches--and don't peel etc. But I guess the shiny option from the factory must have been chrome. So if want to show the dear old thing in the category of "Delux 54 AD Truck Most Indistinguishable From Factory Original In The Whole Darn Universe" ya'd better show up with the peely kind if you don't want to give the judges apoplexy. But if you want to drive it, stainless is probably the way to go...
