I thought I had the correct part numbers but bolts are alot different from what I have .part number I have is (n91069001) as you can see in pic it has like a spline on the head for tighten but original dosent .also dosent have the little teeth parts for sitting in bracket . Hope this make sense and thanks for eny info you all have
