As Crackedback said, "packard 56" I have bought them from "Clips and fasteners" but I recently noticed the price went way up. You have to be careful to get the correct type. Some Mopar connectors the terminals MUST be wrapped around over the sides instead of folded over the top:

These over the top will NOT FIT some types of Mopar connectors

Usually you want this type, rolled in on the sides:

Yes. I agree. Everyone says Packard 56, but I saw the same thing on my original harnesses. The female terminals are like the lower one - contact is made by the rolled sides. Will see if I can find the proper name for these later - packard 56 female AFAIK has the leaf spring center as in your top photo.
