Cliff R. was kind enough to design a protector for my Mary Shelley's Frankenstein Ice Cave Saucer, which was getting pretty chewed up.
(He already had protectors available for the Geneva and Sarcophagus Holes.)
I've attached pics showing the installation. I think it looks and plays great.
I'm sure that they are not yet available from parts sellers. But I bet if you contact Cliff through his website (www.passionforpinball.com), he will be able to hook you up.
