45 degrees doesn’t work because of the pattern of the TX-2 (which is basically an 8 bolt pattern, minus two bolts). You are best rotating 22.5 degrees, which puts you half way between the TX-2 pattern.
The plate I make bolts onto the bottom of the Yaesu (the mounting bolts are counterbored in), and has the TX-2 mounting pattern (or I also do it for the Ham IV, which is four 1/4-20 bolts, and can be rotated 45 degrees). Has the advantage of doing all the work on the ground. Btw, the stack of the adaptor and the g-2800 comes out about an inch shorter than the TX-2, and smaller in diameter
