My understanding is that 16" Anco blades were standard. No way can I go with black. I could buy the stainless ones but I am already $50 deep in wipers. Need the $5 fix. Thanks for googling. I called Classic Industries and they have zero clue. Said that the ones I purchased are for the stud mount ended wiper arms. only the e body arms were stud style. They actually show two different styles of wiper in their catalog for 70 b bodies.
