The 01323 Kit is a bolt-in kit for 3" webbing for SFI applications only. It is designed in such a way that it can be bent with pliers to a specific angle for acheiving a perfect harness installation. The most common use is for shoulder belts that need to be bolted into a harness bar. Will need the 3 bar slides that come with your shoulder belts. If you need those as well, you need the "Wrap Kit".
