1970 318 dip stick tube broken off

I had to drill mine out i couldn't get it to budge with an easy out. I started with a smaller drill bit and worked up to 3/8 it eventually got so thin it pulled out around the drill bit. I cleaned the whole out with brake cleaner and compressed air. My engine is out of the car so I didn't have to worry about the oil pan being on, I wouldn't suggest doing it this way with the oil pan on.
