HI
Above are images of my seat belt brackets lifting the belt away from the shoulder and neck but also creating a favorable angle over the rear shelf to stop snagging. Dead easy to fit, just undo the retaining bolt holding the factory bracket in place, if you wish to leave this for possible future use just let it slip back toward recoil, if not wanted cut it off. Then bolt my bracket on using factory bolt and plastic cap.
I have to come up with something similar for my Plus 8 now.
