I have added this article to my page as the American Jeepster Club site that used to host this seems to be defunct. If you are the author, please reach out to me so I can give proper credit to your work.
The Jeepster was at times a hodge-podge of parts. After the purchase of Kaiser by American Motors, it seems they were put together with spare parts. To help you determine what you have in your Jeepster, or what to look for, we have provided our best cut at the specs. on the different years Jeepsters were in production. You can also see the production numbers (rough) for each year.
