Rusted out rear jounce bumper

What is your question?

I have a 2008 Saturn Vue. I recently noticed that one of my jounce bumpers has rusted off and is sitting at the bottom of the coil spring. I bought 2 new ones to replace them but noticed that the place it attaches to has rusted through. Is there any way to repair the mounting point or could I drill a hole in the bottom control arm and mount it below? The rear suspension diagrams I've seen online show the jounce bumper mounted on the bottom. Is it possible there is a part redesign I'm unaware of? I'd appreciate any advice out there.
