Anyone have an idea as to why my replacement frame has 4 large holes in it but the old one don't? These are in the sides of the frame. There is one right behind the trans mount on both sides of my new frame, then about 25 inches back from that is another set. Convertible frame maybe? Im a bit worried. Hope the pictures help. Danny PS The first frame picture is where the clutch and flywheel went through it, Ive never seen this before. photo (8).jpgphoto (7).jpgphoto (5).jpg
