Is this wiper blade holder the type that would have been installed at the factory on a 67 B-body or is it more likely an aftermarket replacement? Of all the Mopars I have ever owned, I never had one that had the wiper blade holders with the part that I have highlighted in the ellipse. But, that being said, this is the first Mopar I have had older than a 68 model. I need to get a replacement as this one is actually broken at the hinge but I just want to be sure this is the type my car should have.
