Wally your ignition should be on the dash like most classics, I'm assuming. I would only recommend a little graphite on locks or ignition key switches. There are "liquid graphite" solutions that is just dry graphite suspended in a solvent carrier that will flash off quickly, which is what I prefer to use. I would be prepared to change out the old one for a new one. It's a pretty straight forward replacement and you probably already know that. Just remember wire colors going to terminals etc., maybe write it down for reference. That switch shouldn't be more than $25 depending on where you are located.
