This is the RAM Wedge, you basically place it in a hole that is 3/4-7/8 in diameter and start tightening and the base expands to fit firmly. You can mount fishfinders, rod holders, GPS, or anything that you can make accept a 1" or 1.5" Ram socket.
This is the RAM transducer arm. it is compatable with the 1" RAM ball.
If it were me, I would mount your Gear Tracs on the black mounting boards where you want them, and attach the RAM transducer arm to that. You would have to get the T-Bolt that fit the Gear Tracks though.
