Just spoke to one buddy and he said there was a guy in the city that rebuilds them. He got him to do the one on his GN.
At least we know where to send them. 
I had 2 welded & they both broke with installation so I vote No! 
Would freeing up the tube in the broken ear help in not breaking it again ?
just about every one that i have seen broken has the pin crushed and the nut sitting on the body.
mine has been broken for a very long time, i have been contemplating on having it welded, IF i do get it welded i WILL loosen the pin some how (but not too much) in hopes of not breaking it again.
