After a "good" friend had borrowed my trailer, the ball coupling was gone and we needed as soon as possible a replacement. In other Internet retailers were not able to present their products so that one was sure exactly this spare part is right for our followers. I punched the details of the old clutch Amazon entered and accurately obtain the correct coupling. We need about shipping and packaging not discuss, as always with Amazon example, fastest and perfect delivery. Can I just recommend, clean quality and price with no competition !!!
