CHASING DOWN NEW THREADS
If you don’t have a thread chaser for the right bolt hole size, it’s pretty easy to make one. You can modify a bolt of the correct size and thread pitch. Cut the head off & cut a groove in the threads, length wise. Now put it in a drill motor to chase the threads. And if it breaks off, it’s easier to drill the bolt out than a broken tap or regular thread chaser.
