.The weld-on-a- "bar" modification is a good solution if you do not care about the longevity of the dog bone bushings. Welding around the rubber deteriorates the bushings quite quickly. However, due to the welded on bar, they can't fall apart. A #1 horse shoe is essentially 1/4in stock. People have used bolts to weld across and also drilled the centre of the dog bone mount and threaded in a bolt with a plate to achieve the same thing.
I went with replacing the stock bushings with Heim joints from Erik's military surplus. Yes, expensive, but that was the last time I needed to touch the dog bones. They will outlast me by a wide margin.
Company that I worked for back in the 80's welded a flat plate on pallets of new Dog Bones. Deuce and 5-Tons got the same treatment. The metal was "Plug Welded" in a 3/4 inch hole, then quenched in water with the idea that the quench helped keep the rubber from separating from the steel. It worked really well for us. We also had hundreds of trucks and drivers didn't do much more than an oil and tire check at startup.
The Heim Joints weren't available back then. AND a pallet of Dog Bones was a cheap purchase back then too...
