If you get these, buy the ones that have an upper sash with D ring and are for a hardtop. They will be less likely to cut into your neck. Heres a pic of the Wesco belts with upper sash mocked in my barracuda coupe. I used the lower outboard bolt hole for the retractor, and made my own angle brackets forward of that as an anchor point for the other lower belt loop. As you can see they attach where the front seat rear support brace is. The second set of those anchors is for my sons 69 coupe.
