I am also looking for one of these cams and a flipper bat for my ALI Rock On rebuild. Is the 3d printer file for the cam available anywhere? I sent a PM to Volgon hopefully he still has one to sell. If I can’t source any of these parts, I read a post on this forum where an ALI Star Shooter flipper assembly was converted to a Stern classic flipper assembly with a Gottlieb 24V coil A-5141. Based on the pictures I saw I think this will work for the Rock On as well, but not 100% sure. If anyone has any information on flipper parts for this unit I would appreciate the help.
