[Star Wars] Has there ever been any indication in the books or EU as to which galaxy in our universe Star Wars takes place in? And/or is there any basis on which to make an educated guess?

Star Wars takes place in a galaxy far far away... which implies it's within our universe. So which galaxy is it?

ET claims his home is 3 million lightyears away from earth, which would place it in The Andromeda Galaxy (I think). Since ET's species has appeared in Star Wars you could argue that's proof Star Wars also takes place there.
