I'm a pinball newbie , and Tron was my first ever NIB. I tried to put the Hallmark Cycles on, but for the life of me couldn't get the plastic sets (that the original toys sit on) off of the ramps. I tried using my screwdriver but that was to no avail as it just kept spinning the nut around too. I'm not the best with tools, so maybe I'm missing something, but can anyone tell me how to do this?
