Rebuilding a S&W 1066 and need the following: safety lever plunger, extractor pin(at some point someone used the wrong kind of punch and damaged it. It works but I'd like to get it back to original condition), and a new draw bar

Sources?  Numrich, Brownells, Midways, etc no luck.

Yes and S&W themselves quit handling parts too!
