I don't believe there are any Molex connectors of that size on that age Gottlieb game. Only the larger size.

But in regards to re-pinning, most are referring to the flat pins like used in a normal in-line 0.156 header connector but are actually used by Gottlieb as the Edge connectors to the PCBs and displays. It is here where you see damage due to the battery alkaline leaks. For those pins, you need no more than a small flat head or Jeweler's screw driver to push the tab in and slide the pin out.

Many "exotic" flat type pin extractors can be easily made by hammering flat an opened Paper Clip and grinding it narrow as needed to fit the slot in the plastic.
