Those are Packard terminals. Two different sizes. 56 and 59. I bought them from this place. I started out with a dozen each of the males. In the end I bought a lot more of male and female because I rewired everything on the motor in both of my cars.
http://www.texasindustrialelectric.com/_packard_terminals.asp To crimp them right on the wires you really need the correct crimper. I bought a set of them from american auto wire. Theyre not cheap but they do the right factory style crimp. Figured it wouldnt hurt to have them in the toolbox for future projects.
If you want the correct color wires you can buy small lengths from a place called wirebarn. They have a website.
