Re: busted studs
You can go to most hardware stores and get an "Easy Out". You drill a small hole into the broken stud then insert the easy out. It is reverse threaded so as you turn in the tool you back out the broken stud. If there is enough of the stud exposed you can also try to cut a slot into the stub and use a screwdriver to back it out. Good luck!
If it can't be broken I'll find a way!
I'm not lost, I'm exploring!
