I recently bought a getaway and noticed after buying it that there was a missing post. It looks like the post screwed into the playfield and was broken off. As you can see from the pictures, it needs replaced, but I can't figure out how to get the broken piece off. I read somewhere that you can use a dremel tool to notch out a line to get the blade of a screwdriver in, but this screw can't be accessed from below the playfield and I'm worried about damaging the top of the playfiekd. Any suggestions?
