to fit to this female one.

it is off a kawsaki gpz 500 rectifier/regulator unit.

and had six 6.7 mm female spade receptacles arranged in two rows of 3, as in photo.

Can't help with sourcing the part, but I recently replaced my rectifier, and my block connector (similar to yours but 5 pin) was molten charcoal. Dirty connections obviously caused resistance which built up heat and melted the thing.

My replacement is soldered in and wrapped in heat shrink. I don't anticipate having to remove it ever unless it's fried, so I see no reason not to solder it in - much better connection.
