Traxstech tbolt on 1775 impact ss

Anyone know the angle needed to mount the tbolt onto the gunnels and if the spacing is enough where the gunnels and transom met to insert the t bolt bracket. I search online and found out that the lunds sportrac angle is 58 degree but might be different for other models. When i measured it, it was 50 degrees. I also found out that some people were mounting the sportrac bracket from lund both horizontally and vertically. This would mean that the trac is 45 degrees. This is the 1775 impact ss. I will be using this for trolling dispy for salmon and trolling for walleye.
