Who knows Wipers and refills? Especially originals

Tim, That's neat. Corrected my first post and took a look the wipers on my 1967 Barracuda. Buttons are there, just very faded. Single button on each blade, like the '66 blades in your first photo. These were on the car when I bought it (1989). So maybe original for '67 as well? Other than the stripe, this was a base model; slant 6, with possibly dealer a/c. Pictures below.

ANCO Anti-Wind-lift Red Dot, although the rubber insert/refills are not. 15"




Was the button the entire retension system, or were there also clips into the claws?
