I discovered that my ignition switch in my 65 Coronet is on its way out this weekend. I want to replace it with an oem unit as the first one lasted 53 years, but I doubt a modern version would. When I search for the part number that I derived out of my parts book, it seems to go from 61 through 68 and pretty much every car for those years. Does that sound correct?If that's the case, then I guess I'll just find anyreasonably priced new OEM unit?Bill Maurits
