Is there anyone who knows if you can buy a brand new one of them because the last one I got the caliper bolts were stripped

 

What are you driving? It's a 98 Dakota, nope. Nothing available new. Maybe ask your local parts store? Don't hold your breath though.

 

I'd find a u-pull-it and pull one off myself.

 

Yep , get one from a junkyard.Or try a rethread ..Sometimes a tap can fix the threads if not overly out of line ..
On my brake caliper pin I had to do that an it worked ..I could have used a Helicoil too but the tap fixed the threads.
Some sell them used on eBay too .
Good luck
