You guys are great! With your tips and tricks, it should be a lot
easier to get the left one out.
One trick I learned after I finally got the right cup out... A drum
sander attachment on a Dremel (or any other rotary) tool works great for
getting rust and other contamination out of the seat before fitting a
new cup. And, yes, I did apply a thin coat of grease to the seat after
I cleaned it out.
