Quick solution for the non-functioning neutral switch: jumper the terminals for the starter lockout, terminals 3 and 4 from the diagram I have, at the switch. This way you'll have your car up and running until you get a switch. Of course, you won't have backup lights, but that's minor. Just make sure to always press the brake when starting in case it is in gear.
As for the fellow with the non-functioning backup lights, drill out the rivets and clean the contacts. Then fasten it back together with some small screws. Heck of a lot cheaper than buying a new switch.
