Believe it or not, that's the way the originals were done as well, at least they match exactly when I've removed an old, soda-stained one and replaced it with a new one. No matter how you line it up, it's going to be off by about 1/8" in certain spots. Usually it's not noticeable by the casual observer (YOU didn't notice when looking at an original, did you?) and should look fine once the glass and clamps are in place.
