Hello everybody, I have a bad vacuum advance on my 1960 Imperial Crown. The distributor numbers are: Chrysler # 1889564 Auto Lite # 1BP-4006-C I called my local Napa and some other stores. Napa even called the manufacturer for me, but with no luck. Neither Echlin nor Standard Ignition list the part. The earliest Imperial that they list a vacuum advance for is 1962 to 1965....the part number is VC 1165. Does anyone know if that will work on a 60 Imperial? Thanks, Jeff Carrothers 56, 59, 60, 62, 64 Imperials
