Here is a picture of the mods i made to my twilight 1.
Strengthened the vertical arm with two laminated pieces of plywood. Also drilled and tapped four extra 1/4 inch UNC holes in mounting plate to vary the vertical arm position. I didn't need to lower the arm by 45 degrees, so i put in extra tapped holes at around 23.5 degree position and two extra(top and bottom) for extra clamping.
