Ryan, I was a bit alarmed as well when installing. Yes, it wasn’t exactly the plug and play I had hoped, but with a little modification, I think you can get the desired look. (Which always seems to be the case with these cars)
Which is why I immediately turned to Wilhoit to see how their restorations appear.
It appears on their restorations, the arms sit high exposing more distance between the body and bottom of wiper arm.
I zoomed in to the photos I attached earlier to highlight this distance.
I filed a flat spot due to @TRP comment about the arms flying off. At least I thought he said arms. I figured a flat spot would be a little better in terms of grip.
