I've got two Cannon manual downriggers for free. I would like to mount these to gimbal mounts. My question is how deep are the original factory rod holders. My options for purchasing these gimbal mounts are 9 or 12 inches. My boat is 50 miles away otherwise I go and measure myself. Thanks Billy Mac
