The Drainage plug for my radiator on my 90 integra LS 2dr droke off. Any ideas on how to get the thing out without damage to the radiator. And were can i get a replacement plug for it

 

just answered in another post, you can usually get one at advance auto or at a dealer for sure, if the ears are broke off see if you can grab around the collar of it with some pliers, if not a small left handed drill bit should turn it out with ease
