I have a couple of non remote mirrors that I can mix and match to make a good one , and another one that needs a new piece of mirror glass . I assume I must endure 7 yrs of bad luck to get the glass out ?

What about getting the pieces apart so they can be replated and polished , can I just pull the pivor ball out , I think its splined in ? I do have a mirror base I can sacrifice if need be .

thanks
