I can confirm what Grand73am said, I had 3 sets of sail panels over the years, one that was in my car originally (a fisher t top car), another from a confirmed fisher t top car and one from a hard top. It appeared as if the factory used some sort of indrustrial sized toe nail clipper or something, they had clean but not precise cuts. Anything you do will look better than factory and as Grand73am said that tab is covered by the t top trim anyway.
