radiator drain cock

I busted the wing off the drain plug in my 97 S10 and was wondering if the plug is replacable. If so, how do I get the old one out and how do I get the new one in? Where do you get these replacement plugs?
Thanks for any help!

Never had to do it myself, but if you can get the plug from the dealer, they should be able to tell you how to pull it if it's possible...

The entire plug is usually just a thread in unit. I think that it uses about a 14mm wrench (9/16).
