    Edward took time from his day on multiple calls to answer a few different questions I had. He called me back promptly when he did miss my call. The shipping was lightning fast, and the setback plate fits perfect, looks great and performs good. The bolt patterns were dead on. I am very satisfied with my purchase and I will not consider another brand of setback plate due to the service and quality product that I received from Vance. I have already recommended this company to a few friends. Thank you, Keep up the good work Vance!
