Magic Molex Ordering Assistant?

Perhaps someone can teach me how to order Molex connectors and/or perhaps recognize what I believe is a fairly standard connector. At least back in the early S-100 days. I have looked online to order but my eyes cross after a bit trying to narrow it down. Perhaps this connector has a group or 'kind' name below Molex to further differentiate it?

I've seen this connector on several Solid State Music boards, and it is very similar, if not exact, to the battery terminal for a CompuPro System Support Board (SSB). The spacing seems the same as a four (4) connector plug for a 5 1/4" FDD or older IDE drive although the pins on this connector are narrower.

The two (2) pins are square about 1.5mm wide, 14mm long and 3.8mm spaced apart. They are not polarized, which was kind of a pain on the CompuPro SSB for battery polarity (it is lightly polarized).
