Help...broke a master cylinder bolt...

Ok was replacing my alt. by way of the master cylinder removal, was getting it all put back togather and tightened on of the master cylinder bolts to tight and snaped it off. Are these replacable if I take of the brake booster?

Thanks!

Actually looking at it, it aperars to be a stud, so I’ll try exstacting it. anyone else have this problem?

That stud is part of the brake booster you might have to get an all new brake booster.
