Set up my Terminator 2, and discovered when trying to level it that the two ends of the playfield were off level, in the opposite direction. It's resting properly on the back hinges/bolts and on the front bar, so it seems that my cabinet is also twisted? Or is it possible for the hooks that the front end hangs from to be different lengths? I don't think the back end bolts could be at the wrong places as they go through holes in the side... Could the front bar be misaligned? The cabinet doesn't seem obviously warped. I tried to adjust the legs to compensate but trying to raise/lower them to fix the playfield results in the cabinet rocking side to side. Is there anything I can do short of sticking a piece of 1/8th inch metal stock under one of the front hooks?
