Do you know what a CJ-8 is? The differences between a CJ5 and a CJ-7? What years an XJ was available? If not, this web pay may help you.

I have searched the web for jeep model designations and found quite a list, including some conflicting information.

If you see any errors/omissions in the following chart, and have proof of the inaccurate information or omission, please and please provide your source for the information. Thanks!
