Oh man, you are exactly correct. I apologize for this. When I bought them, I was told they were for an early A. After you wrote this, I ran the number, and you are right, 67-68 Dart/Barracuda 273/318.
I am glad that money has not exchanged hands, I would have felt horrible if these did not work for someone.
I will contact the person interested, and see if they will work or not. If not, I will re-post with the correct info.
