Often on these old cars, old grease and garbage as well as oxidation, builds up on the internals of various switches, including the ignition switch. This increases the resistance on the circut, which equates to heat, and eventually melting wires.
Something I learned from my old MG days is that you can sometimes carefully disassemble the switch
and clean the internal contacts with fine sandpaper, put in some new dielectric grease, and reassemble. The source of the problem is usually in very close proximity to the melting wires. Replace any melted wires, using soldered connections, and clean or replace the ignition switch.

Good Luck,
