Packard 56

Agree. Chrysler used something very close to Packard's 58 Series for most of the females.
But also used some 56 Series females.

Got this from a link on the Mouser website.

To the original question.
Yes there are different sizes.
For example, the drawing above the wire size for the variaous part numbers on the left is shown on the far right. Unfortunately its in metric rather than wire gage.

Conversion to wire gage for some those that are still being manufactured in this post.

if you're working with the 56 Series, same thing and many retailers will list the wires size its made for. Some terminals may be for the same wire size but are offered with longer or shorter 'wings' for thicker and thinner insulation.
