Hi all

Welcome to the site. Do your stock wiper arms end in a "u" bend (like my 73 and 74 Dusters) or a straight end? Those are the two most common types I have seen. Most new wiper blades come with attachments to connect to most older wiper arms. I have never had a problem finding replacement blades for mine at any auto parts stores. This is basically what mine look like, hope it helps.
