So i picked up an Evo 9 about 2 months ago. Just been trying to clean it up. One issue I ran into is the seat belt clip will not fit properly. I figured it was broke so I bought a new one and that didnt fit either. I had someone look at it and they believe the previous owner had a harness bar and changed the nut. Can anyone confirm from the picture whether this is accurate? What size would the proper nut be?
