Very common on the old thermal reactor engines. There is/was a jig available specifically designed for drilling out the broken stud. If need be, there are also Time-Sert kits that make thread repair fairly painless. 8x1.25
Caveat: Drilling out a broken stud with a jig is courting disaster...don't try it.

Henry,
I have a helical thread insert kit but I want to avoid using it if I can. If I replace the studs I want to use new parts. If a stud is going to break I would rather have it break now as I'm pulling the motor out for a long needed service than have it break when I'm a thousand miles from home on a trip.
