I bought an F-14 with the same issue, I got my parts from Action Pinball, the prices were not great but Ray give good CS. I was missing the actuator rod and spinner that connect to the leaf switch. I also needed a few of the ball roll over switches for the ramps. I could not find them anywhere but he was able to sell me an alternate from other Williams games (jungle Lord, High Speed etc..). Call him. Also look at other system 11 games the leaf switches out of those should work. GL
