'68 Barracuda Notch

Are you talking about the shoulder portion that attaches to the roof? If so, I already had the provision for that in place, so all I had to do was poke a hole in the headliner and thread the bolt in.
Nope floor mount. I made and welded anchors in the roof. I have a 69 notch as well that i copied the location from. The outboard sides of the belt in the rocker panel. Theres 1 threaded hole on either side. I'm assuming that this is where you mounted the retractor box. The way you have it all mounted is so clean it looks like a factory install this way, so i wanted to copy it. The belt mounted forward of the retractor box. Howd you mount that end of the belt? since theres no hole or mount for that.
