I was just doing some research on wiper arms for my 64.5 coupe and trying to determine if the ones that are on it are original. They are trico and though it?s only part of the arm, the rivets appear to be the same as the bottom one in your image. And they have a angled turn at the end, which seems like it may be different from the ones I?m seeing online under part C1SZ-17526-A. I can?t find that part number anywhere on the arm.
