Looks like a "female" pin terminal socket. It's an old style crimp that folds over the insulation and the wire. I have a crimper that does that. It originated with the telephone industry in the 1920's.
This post is an example of how you look up the terminal part number in the Electrical Wiring Diagram. This other post is an example of the earlier steps, navigating the wiring diagram down to the right system and connector.
Thanks guys for all the recommendations. Eventually after contacting a houston automotive pigtail company here who said they carried it, I just wen to a junkyard to pick it up. Then it came with the rear axle beam assembly that I purchased too. So ended up not needing to do my original plan.
