Bulkhead Disconnect Plug - Wire Change?

question on the main harness plug on firewall

If you need to replace a terminal, the female terminal shown above is sometimes called a Chrysler type terminal. It seems to be the same as a 'Packard 58' whereas Packard 56 has a flat tongue. For '67-68, all of the original ones I've seen so far are the type 67Dart273 shows. But repop harnesses sometimes have a mix.
