The ideal situation for bolt-in harnesses is when the bracket can pivot on the bolt to allow for perfect geometry. This pivot action allows the force applied on the webbing to dictate the orientation of the bolt in bracket achieving the desired orientation of the bracket.
Sleeves must be used in conjunction with a washer on one side. See picture of assembled bolt in setup. Sleeves are available in different sizes for different bolts.
Note: if you are using a B24 bracket, you will need the sleeve specific to that bracket.
