you would have to measure straight across from where you want the crossmember to weld to on each notch, then measure from the center of the imaginary straight crossmember to the center of the angle.
you could then take 1/2 of the 47" and get23.5, with these two numbers you will be able to figure out the perimeter of a triangle, once you have that multiply it by 2, and you will get the length of tubing you need to cut
