You might try the vendors and see if any NOS switches are still available but they will be expensive.
One of the vendors has reportedly repro'd the contact plate to start repairing switches but I have a couple of concerns on the plate I saw. Biggest one being it is seemingly made of ordinary brass which has a much lower melting point than whatever composition of phopho-bronze material the original plate is made of. Since even the original contact material has melting issues I would wonder about the longevity of ordinary brass contacts holding up if it is used in rebuilt switches.
It has also been reported that there is a factory bulletin suggesting a relay be added to the start circuit to get the heavy senior model solenoid current out of the ign switch. I have yet to find that bulletin but the idea is a good one. Hete is a diagram showing options on where and how to add such a relay. An ordinary 30/40 amp contact cube relay from the parts store would do the job.
