Quoted from LesManley:
I finally took the plunge and decided to install the chest opening mod. Physical install went fine, but I cannot get the arm to move the lid at all. I have the newer flex rod assembly, so I followed the video instructions as best as I could but since that is the ball and rod version maybe I am missing something? I even tried modeling it after the pics of VolunteerPin above. I have the 4 prong wheel and his is the two prong, but I tried positioning mine like his and like in the video even though, but still nothing. From a glance it seems like my flex rod is too long and has too much slack to make anything happen with the chest, but with these flex rods you don't trim it, so I am kind of at a loss. Anyone have any ideas, words of wisdom, encouragement? I really want to get the game back together and start playing it again.
Can you post a pic of what you are seeing as far as the rod alignment?
You can trim the flex rods, but they should not need to be. There should be enough adjustment on both ends to give you 1/2" or more of play. Ideally, if you can take a video of what is happening above and below the playfield that would help.
