No, mine worked perfectly. It only took about 20 mins and I didn't have to cut anything. I did notice that they are not as solid as they were, they sort of float arround on that soft rubber bushing. But I don't think they will move.
Kawi12R, I had the same results. Didn't have to trim anything but the signals are just a bit looser than they were before, but nothing to complain about. Like you said, I don't think they are going to be moving around when going over bumps or anything. I love the way it looks.
