I am putting my car back together and just glued in the headliner and now I am installing the trim. I know I'm missing a few pieces but I thought I had the correct long pieces that go across the windshield and back glass. Are these the right pieces and what am I missing? I know I am missing the pieces running down the back of the sail panel. I have two more of the little corner pieces. Not sure why two have holes in them and the other two don't. I assume the two with holes, which are steel, are original. Any help would be very much appreciated.
