It's delicate and expensive.  The steel plate you're moving has a
ceramic plate glued to it.  The screws are insanely tight.  I
recommend inside, with a good light and make certain that you have
the right size of Phillips, in good condition; and use lots of
pressure so it doesn't wipe the socket.

The top comes off by cutting around the silicone and then exerting
very firm tension on one corner.  As it starts to peel use judgment
so as not to break the cover.  The cover will sit back on and seal
very nicely, and stay put in any normal driving but still be
removable later.  BY DOING THIS YOU WILL DESTROY THE CORE VALUE OF THE AFM.

I don't think it makes much difference, but I think it's preferable
to move the plate toward the wiper shaft.
