Not sure if this helps, but in WMS pins of this vintage the playfield and headbox molex connectors are 0.062" and the ones that go to the original PSU board and transformer input are 0.093". These dimmensions relate to the diameter of the pins. I have purchased from Ed at GPE and he was helpful and had good postage rates. His website
http://www.greatplainselectronics.com/ has pictures of all the connectors so that may help you identify what you're after.
I also have a data sheet showing molex connectors with dimmensions and part numbers if that would help - pm me your address and I'll send it your way.
