The box hitch is 11" long, the front edge is wrapped with a piece of 3/4x1/8 flatstock to duplicate the real thing. This box comes 2-1/2" square with a 3/16" wall. The bottom tie-down loop is 2" wide x 3/8" thick and completely welded all the way around each ear. I found some nice 7/16"x3" long, grade 8, fine thread bolts and nuts(Fastenal) to replace the shorter originals. These hitches can be made with or without the bottom loop.
The standard flat hitch is now made from 2-1/2"x1/2" flatstock. I placed a 1" drop to still allow the hand crank to swing. By increasing the main flat to 2-1/2" wide, it allows the 2" wide bottom loop to be narrower allowing for a complete weld around each ear. Same with the top brkts. A bead of weld completely around the outside. Also shown with the new grade8 bolts. These can be made with or without the bottom loop.
The last setup is the single tie-down loop. Same tie-down as the ones I made for the side torque tube pads.
