The ranges shown match neatly with the engine numbers found in our list of Surviving CJ-3B Jeeps. Interesting features of the records include the fact that production in a given month may be as little as one unit (February 1965) or zero (April-May 1965).įor 1963-64, engine numbers in the 3J (L-head) and 4J (F-head) series are also shown. The two possible prefixes (573) are also shown. The specific changes represented by these terms are unknown.Īfter mid-1963, the format of the records changes, showing the months vertically for a given model, as seen below. A couple of specific CJ-3B VIN's are listed as 'Final Old' and 'Face Lift'. The pages that we have available for 1960-63 show the serial numbers in the format seen in the example below, for model 57348 (CJ-3B). For a summary of CJ-3B VIN's and annual production figures from both sources, see the CJ-3B Serial Numbers and Production Figures page. As we have speculated before on, the discrepancies might be due to some types of production not being included in the AMC figures, or to missing numbers in the series of serial numbers (meaning that the production totals as seen above could be too high). These figures are somewhat different from the CJ-3B production figures collected by American Motors in 1977. Note: the easiest way to date your serial number may be to find its position in our list of Surviving CJ-3B Jeeps. Annual production totals (based on model year) and serial number ranges have been summarized and included on the CJ-3B Serial Numbers and Production Figures page. The 1960-61 figures included below correspond exactly to the earlier Norton Young figures.Įach of the serial numbers below would be preceded by the prefix 57348 (before 1963) or 8105 (after 1963). These records cover the years 1960 to mid-1967, and comprise serial numbers and production totals for all models, broken down on a monthly basis. The original documents were apparently rescued by an anonymous collector, from a document retention room at the Toledo plant which was demolished in 1983. A new set of Jeep production figures has been located by Keith Buckley, who has compiled the table below showing the CJ-3B data.

The Willys-Overland 1945-61 production figures collected by Willys employee Norton Young and transribed by Charlie Weaver in the 1990's, are considered pretty accurate, but do not cover the last six years of CJ-3B production.
