That looks like a cast iron piece with the shock mounts welded to it. It would be best to replace it. If all else fails I would take it to a welding shop and have it welded. Ideally they should heat the whole piece up before they weld on it and let it cool very slowly. I would not be comfortable just welding the break straight across. A 3/16" fish plate spanning the break would be needed. Even then it could break just beyond the welded area.
