1970 318 dip stick tube broken off

If you're doing this without removing the pan, coat a tap of the proper size with grease and thread it into the broken off stub. Grab the tap with vice grips or something similar and pull it out. If you don't have a tap, you can also use a big screw or dent puller type slide hammer. Next time, don't "wiggle" the tube to loosen it. Put a tapered punch into the tube, grab the top of the tube with vice grips, and then rotate the tube as you gently pull it up and out.
