Early A shoulder belts?

The other day my wife and I were driving the Barracuda around town. When we arrived home she told me she felt frightened without seat belts. So, it's time to install them but I feel lap belts aren't that great. Has anyone ever attempted to install shoulder belts in an early Barracuda?

I haven't done it to my 65 Barracuda yet, but I WILL be installing 3 point belts in it when I redo it coming up in the next year or so. I have used 3 point belts from the link below in several Mopars I had in the past, and was very happy with them. One was a 64 Belvedere wagon that never had shoulder belts. I will make my own mount for the shoulder belt attachment while the headliner is out. It's not that difficult.
