I have been toying with the idea of installing a pair of 5 point harnesses instead of regular seat belts. I have factory bucket seats, I like the style and I believe they are safer than a stock seat belt (correct me if I am wrong please). Does this require doing a full roll cage or can I put a single bar behind the seats just below the rear window that weld or bolt to the frame? Or are there versions that you do not even have to do that but are just as safe as a typical 5 point? It seems like I have seen a lot of people with 5 points without a cage or even a bar behind the seats to attach too. Thanks for the thoughts.
