95 7.3 diesel glow plug stuck

I replaced the glow plugs on my 95 F350. One of them broke and is free spinning. Anyone have any suggestions as to how I can get it out without pulling the head. A local shop said not to worry about it as long as I don't have any problems starting, but knowing it is there bothers me.

I snapped one off a few years back. I was lucky to have a little sticking out. I soaked it with some penetrating oil then tapped it in ever so slightly that broke whatever was holding it in. Then it pulled right out.

A slide hammer and a "hook" attachment should pull it right out. Put a Vice-Grip on the GP, and use the hook on the slide hammer to pull it out.
