The information was obtained from the following manuals. 1966
Universal Parts List, 1949 CJ2A CJ3A Parts List, 1965 Universal
Service Manual, 1953 CJ3B Parts List, and 1968 CJ2A CJ3A Revised
Parts List. For the sake of uniformity, the serial numbers
listed in the database are the effective serial number of the
change. The manuals sometimes specify effective numbers and
other times list "up to" serial numbers. In the case of "up to"
numbering, a 1 was added to the serial number to make it the
effective number. CJchange.txt is a
tab delimited text database for downloading. The information is
best used by importing into a spreadsheet or database program
that will allow it to be sorted.
