The Strange Science I purchased did not have a topper. After a long search, no one had one for sale, so I just bought the neon bulb. I figured I could just attach it to my machine without the plastic cover. However, after looking in the backbox, I can't see any way to anchor the neon tube to the game. I assume there are some sort of parts that hold the tube to the backbox. Could any of you that own a Strange Science with a topper post a few photos of the way your neon tube connects to the machine? Any advice would be appreciated. Thanks.
