Good deal. Luckily you only had one snap off. Hope you used never seize on the new threads.

Thank you for posting Charles .
injector socket size is 30 mm deep socket.

Once you remove the injector it’s a large enough hole for the magnet to go through and bring up all the broken pieces.
I recommend having flexible magnet tool ready just in case, because some of the injectors are hard to get by themselves let alone hard pole magnet to go through.

Air compressor will also help blow out stubborn pieces. Direct flow of air into glow plug hole and catch broken pieces with gauze or wire basket over injector hole.

Wish there was some procedure that was easy when one has one glow plug totally seized and immovable, and inaccessable, and other that disintegrated the housing and left the threads in the head.

Place a heavy grease and Vaseline soaked rag through injector hole. Over drill and tap it out and use thread replacement. Vacuum out the area. Pull the oil soaked clothe slowly. Blast high pressure air. Look with boroscope and if fragments remain, blastout with oil or soapy water until clear.

much easier to take that one side of the cylinder head off,
There is no room in the truck for drilling and tapping.

The worst one I fount was the drivers rear plug. There's just no room.
