brass core plugs

[robert.dambrauskas@kodak.com]

Thanks to all the listers for the info on freeze plugs , but now I am 
going nuts trying to find brass plugs to buy ! D.T. Gebhard 's reply said 
he had his replaced by a machine shop . I think that is a great idea but 
it looks like the ones in most catalogs are not brass. Where can I get 
them? Thanks in advance for the help.
