Now that I'm FINALLY driving the '67 it seems the ignition switch is sorta sticky and also loose in the dash. Is there a trick to tightening it up? I shot some graphite in there hoping to ease up the action, but it still seems to stick as well. Do I just buy a new key switch, and from where, or is there a way to get it back in shape? I don't think it's been replaced in 22 years...
