Not Ranked
This is a toughie if it is in the frame itself. You would be well advised to remove the glass before working on the holes.
Get a Metric bottoming tap (or the next "inch" size) carefully drill and tap to next size.
The threads are SAE but the next size to remove the least material might be Metric.
I feel your pain, but it can be fixed.
