If you convert to cm this site will calculate focal length for you: http://www.satellite-calculations.com/Satellite/reflector.htm
I've since sold my 5' dish but I drew it to scale on graph paper. Once I knew the focal length I drew in the arms. I measured and scaled them up. The key measurement is between the bends. In my case the arm mounted on the edge of the dish so it was easy. Good luck!
