I had thought that the clamp itself was damaged but it seems okay. I just removed the bolt. It is indeed stripped quite badly. Looks like an aluminum bolt. M5 15mm bolt w/ 0.8 thread pitch. I'm guessing the nut is okay. I don't know how to remove it anyway. So I'm guessing I can just get a new bolt and then figure out how to get it all back together and adjusted.Thanks for your help

The higher grade components often work better longer and can have more of their intended performance level brought back with periodic maintenance when compared to the more basic grades.
Is there a reason why you are thinking of a replacement? Andy
I'll answer that last question first. I thought the clamp was broken and the clamp seems to be part of the derailleur hence the search for a new one.
As for a desire to upgrade... well why not lol. I'm coming from a performance car background and "if it ain't broke make it better/faster" is one mantra in that world. But practically speaking I don't feel the need to upgrade. I don't do any trail riding or racing. I just ride my bike for health. Read my reoly to Aubergine for more info. Thanks!
One question for either of you. Do you know if the nut would typically be aluminum or is it more likely to be steel. NVM, I can test that with a magnet I think. If the nut isn't aluminum I think I'll get a SS bolt.
