When I put the 23E Date Code for my 1963 Ranchero into the online VIN Decoders I get back a production date of May 23, 1962. Were the 1963 models produced that early in 1962 or should the year be 1963? The VIN number indicates the Ranchero was the 69,412th vehicle produced at the San Jose plant. I'm not sure how early in the production run that would be.
