It's extremely important that the shoulder belts go from the harness bar, directly over the collar bone, to properly protect the spine, as in the photo.i recently converted my car to have shoulder belts. where was the shoulder belt supposed to go from the factory- mine goes around the outside of each seatback and this does not seem right
(i have seats from a '70, as in they do not have a headrest but are taller if that helps)
