67 Dart shoulder harness anchor?

My 67 2 door post did not have them. My 73 has the optional shoulder belt that you can use. I can't stand how high the shoulder belts mount, goes across your neck area, and I'm tall.
I run the 67 at the track and wanted something in addition to a lap belt so I added my own mount in the post. It's not factory pretty but it will keep my face from hitting the steering wheel.
