Lonka,
That second picture shows some very poor welds. I'm wondering why those welds are there? If it broke and you fixed it, then I apologize for my critisism, but those are the welds of a beginner. I can't believe that a company would try to sell an impliment with welds that look like that.
Because of those welds, I think somebody has done some modifications to your wheel height and placement. I wonder if that is the original bracket or one that was similar that they were able to make work. If it is the original bracket, I really gotta question why it was welded. Do the other corners have the same looking welds? If it's just the one, then it's likely that it broke and sombody welded it back together. If they are all welded up like that, then there is your proof that a modification has been made and there's nothing you can buy to fix it. You will have to undo the modification or create one of your own.
Good luck,
Eddie
