The CJ-3A is one of many models of the flatfender Jeep built by
Willys. See the Pictorial
History of the Universal Jeep on the CJ-3B page for pictures of all
the different flatfender Jeeps. About 130,000 CJ-3As were manufactured
by Willys Overland in the late 40s and early 50s. The CJ-3A is very
like its predecessor the CJ-2A. At
a glance the major difference is the
windshield frame. The CJ-2A windshield frame is constructed with a
tubing framework. The upper corners of the frame are square. The CJ-3A
windshield frame is constructed from rectangular tubing and the upper
are rounded. The CJ-3A also has a vent in the panel below the glass.
can be swapped between the 3A and the 2A so this method of identifying
the CJ-3A does not always work. A more foolproof method involves
the length of the rear wheelwell. The CJ-3A advertised increased space
for the driver compared to the 2A. This was accomplished by shortening
the rear wheelwell and moving the drivers seat rearward. The length of
the 3A wheelwell from the top front edge to the rear of the body is
The length of the 2A wheelwell is 34". An excellent article, The
CJ-3A Universal Jeep by Reed Cary, can also be found on the CJ-3B
page. Another very similar Jeep is the
M38 is the military version of the CJ-3A. See the
page Late M38 and CJ-3A visual differences
for a list of some of the differences between these siblings. Another
close sibling is the more rare CJ-V35/U.
This is another military Jeep based on the CJ-3A.
The 1949 CJ2A/CJ3A Parts Book has several good illustrations showing the CJ-3A. Much information can be obtained from studying these illustrations of the 3A. Click on the illustrations below to enlarge.
