TC bushing welded cups are rusted out
 

While removing my TC bushings. The welded metal cup that holds the front of the bushing in place came off because it was rusted out. Does anyone have a fix for this problem other than having a new cup fabricated and welded in place. I'm replacing these with the G-force ball and socket kit in the front and rubber in the back. The cup on the back side is ok.
Thanks!
