The clip-on belt retractor doesn't last very long so I got some regular retractors. I had a couple on my 66 hardtop. If you note the picture of the clip-on types, the belts come thru the seat, not from the side like a Mustang belts are installed. With the side mounted retractor, the belt ends sometimes get stuck in the door when you close it and the retractor housing dents the "hockey stick" trim on the outer side of the seat rear. Still, the side-mounted are better. The long strap covers seem to work well but aren't original. When you get down to the bottom line, almost anything is better than no device. (I remember back in the 1960's when we would see a belt hanging out a car door, we would cut it off. We were "nasty" back then.)
