WYOMIKE, $ sink and I have started working on a VIN project since there are a lot of questions relating to VIN numbers, month/year of manufacture, paint and trim, etc. I've created a PDF document (that is a work in progress at this point) that is a guide to where VINs / serial numbers, engine codes, and paint and trim codes are located and what they mean. I will be updating it as time permits. The document is a 750 kb file located HERE, you'll need a PDF reader to view it such as Adobe Acrobat, Foxreader, etc. The starting VIN for each month of Jan 1960 through June 1967 is documented well, but the prior and later years appear to have little documentation relating to what serial numbers come from what month or even year. We are attempting to help narrow down the month / year boundaries with your help. We thought while we were at it, this may also be an opportunity to help narrow down when certain production changes occurred (like shackle reversal, snorkel cutout, etc). We're asking for your help. If you would like to participate in this project, please pm or email the following info to either myself (I prefer email, I'm not good about keeping my pm box cleared), WYOMIKE, or $ sink. You can post it here, but if you want to keep your VIN from being associated to you on the WWW I would suggest pm or email. We are looking for any of the following information should you choose to contribute: 1. VIN #? 2. Month/Year of manufacture from dash tag? 3. Model year registered as? 4. Factory Front Shackle Reversal (Yes/No) (Early CJ5's came with the front axle shackles to the rear)? 5. Model 25 or Model 27 front axle? 6. Snorkel Cutout on hood (Yes / No)? 7. Windshield Frame Configuration (top mounted wipers, bottom mounted wipers with top of glass flat, bottom mounted wipers with top of glass arched)? 8. Large or small front turn signals? 9. Tapered or flanged rear axle? 10. Underseat or rear mounted fuel tank? 11. Hood mounted reflectors, front fender mounted markers, no markers / hood reflectors? 12. Windshield washers? 13. Single / Dual stick transfer case? 14. Paint and Trim codes? 15. Battery box cover on cowl? 16. Bow sockets on rear body corners? 17. 12V / 6V? 18. Foot starter button / key start? 19. Wiper (1 or 2) manual or electric? 20. Hood safety latch / prop rod? If there are other production changes we should try to track, please let us know. If you come across other info that may be useful to this project, please submit it. If you find any errors in the above document, again, please let me know and I will correct it. EDIT: Added this information to this post so it would show up on the first page of the thread (since all the VIN threads have been merged). I'm thinking about getting some of the decals advertised here, and was wondering if there is a way to determine the approximate date of manufacture from the VIN number?
