Packard 56

Trying to repair some bad connectors in my wiring harness. Have some 14 gauge, 16 gauge and 18 gauge wire. Connectors are the Packard 56 ones and I this is my first time to replace this type of connector. Is there a different Packard 56 connector that is used with each wire gauge or will a Packard 56 connector work with any size wire?
