BWDart , I agree to a point, however if your car is a hardtop and not a post sedan car, get the ones with the 8" upper sash as shown in my pic, because the belt on a hardtop mounts higher up on the roofline, and not on the door post like the sedans do.
If you have a hardtop and you spec belts without a sash to lower the D ring, then unless your 7 foot tall, the belt will cut across your neck. Hardtops need the sash to lower the seat belt D ring because of the higher mount point in a hardtop.
See pic 2 of a wesco belt mockup with sash in a 67 barracuda shell. The plan is to weld plates up inside the roofline where the coat hooks were, and add the homemade mount brackets for the other belt attach point.
