How can I tell the difference between the two? Not the frames, only the fabric. My friends early BN4 came with the correct frame, but also a new top in a box with no numbers on it. It just doesn't seem to lie well on the correct top frame. We snapped the top on along the back, positioned the frame, then laid the material up and over the frame, and pulled it forward. It seems short, and, it's hard to explain, but, if we had the wrong material on the right frame, I think this is what it would look like!
