Our list of Surviving CJ-3B Jeeps includes Jeeps and their owners in order of serial number.
The CJ-3B serial number (equivalent of the Vehicle Identification Number or VIN) is found on a plate under the hood on the right side of the firewall.
This plate is from a 1959 model. See also a 1953 Willys-Overland tag (CJ-3B number 12!) a 1954 Willys tag and a 1965 Kaiser Jeep plate.
Reproduction plates in various styles are available from dataplates4u.com.
In most cases (other than 1953 models) the serial number (without the prefix) is also stamped on the frame. See photos of Stamped Numbers on CJ-3B Frames.
Willys Service Bulletin 52-79 dated December 26, 1952 explains the meaning of the serial number prefixes Willys used from 1950 through 1954, such as 453GB2. Bill Norris found the document and provides this information from it:
First number indicates the number of cylinders. Second and third indicate model year. First letter indicates basic chassis model. Second letter indicates body type. Fourth number indicates series in any one model year.
For example, the first 1953 CJ-3B, with VIN 453GB2 10001, was part of the second series of "GB" Universal Jeeps in that year. (It was produced before the final CJ-3A which had VIN 453GB1 20617.)
See also 1954 OB Serial Numbers for the first 2,600 units in 1954.
The 57348 prefix which was used starting in 1955 has the following meaning, according to Service Bulletin 328 dated October 18, 1956, provided by Todd Paisley and titled "Identification of Willys Vehicles":
First two digits 57 represent the Universal Jeep line. Third digit represents the body type (3. CJ-3B Open Body, 4. CJ-3B Stripped Chassis). Fourth number represents the engine type (4. 4 Cyl. 134 cu. in. F-head). Fifth number represents the drive (8. All 4WD). (For more details from this document, see also 1954 OB Serial Numbers.)
Mid-1960's numbers with prefix 8105 are interpreted in Kaiser Jeep 1960-1967 Serial Numbers.
Note: Figures published in the Standard Catalog of 4X4's by Robert C. Ackerson, show smaller totals in the 1950s. Missing or duplicate numbers for some years throw their accuracy into question. Their source is unknown.
Engine numbers may help to establish the year of a Jeep, but only if it still has the original engine. The number is found on the front of the engine block (left). See Plotting Engine Numbers for details on identifying original engines. Comparing an engine number to those shown in Surviving CJ-3B Jeeps will also give you an idea of whether it is likely original.
You may be able to date a surviving CJ-3B using the chart below. Your information may not match the figures below, for several possible reasons:
You can also date your serial number or engine number by finding their position in our list of Surviving CJ-3B Jeeps. Please also consider adding your numbers to the list.
Dating a CJ-3B by Interior Details can provide a an idea of whether you have an early, middle or late period CJ-3B.
Stamped Numbers on CJ-3B Frames can indicate your serial number (but not including the prefix, and not for 1953 models.)
The axle assembly dates, if you can find them stamped on the raised area around the axle shafts, can provide a more accurate and reliable indication of the age of a vehicle, since they are less likely to have been replaced.
