I did a playfield swap on my Phantom of the Opera. I think some of the parts I have are incorrect. Could someone tell me what is right? When I launch the ball, and it goes up top, when it hits the left side, does it hit a bumper or a wire gate? Mine has the gate assembly but no wire gate. The ball hits the little rubber posts at the top left side. Could someone snap a picture or tell me what is correct? Thank you for your help.
