Broken Grease Zirks

[Crike]

I've broken both grease zirks on the base end of the steering cylinders. One of them broke off inside the pin. I was unable to drill it out with a left handed bit so I ended up buying a new pin.https://www.dropbox.com/s/as5gu85aqw7aa7e/Missing Grease Zirk.jpg?m, https://www.dropbox.com/s/nzp42ggk03csa9p/Broken Grease Zirk.jpg?m, https://www.dropbox.com/s/1k9hy8gwnlfnrzp/New Grease Zirks.jpg?m
