We apologize that you received the wrong clamp. We thank you for your order and normally request photos at time of order so we can ensure you receive the correct part, you were unable to do so and we sold you a vband clamp. The correct part was shipped but it is sounding like you need a tbolt clamp. We have tried to contact you by phone and email several times to get you the correct part but have been unsuccessful. We would like the opportunity to make this right with you! You can contact us via email or phone and we will get you the correct part.
