I don't know and I don't know lol. I did not do the art, nor the trackball or the plexi around the trackball. It was given to me as seen in the first picture. I assume that's where the ball was for the golden tee and it was as good as they can get on a cheap conversion art? As I said, I simply was asked to add both Player setups, install buttons and wire it up. Snazzy little setup non the less. I think the guy just wants it in working plug and play condition.
