Guest imported_Duane-Heckman Posted September 23, 2006 Posted September 23, 2006 Date Code Manual I have just finished a new reference book about date coding systems for mid 60?s thru early 70?s GM cars. Below is an excerpt from the book that explains what it is about. Mission Statement As the interest in vehicles with original or correct components continues to climb, the ability to verify these pieces becomes more and more critical. Most parts, including major drive train components, not only have part numbers stamped or cast into them, but are also date coded. Therefore, an understanding of both part numbers and date codes is needed to verify the ?correctness? of these parts for any given vehicle. The goal of this Manual is to familiarize the buyer with the various date coding systems used throughout these vehicles. The hope is that this knowledge, combined with a familiarity of part numbers, will give the buyer the ability to accurately determine which parts are correct or incorrect for vehicles built during these years. Four major items will be included within this manual;1. There will be a discussion regarding the Fisher Body ID Plate, which is the ?key? to understanding the correctness of all date coded parts on a vehicle. 2. There will be photographic examples of each type of date coding system, whether it is cast, incise stamped, ink/paint stamped, or is printed on a tag, and an explanation of how to decode them. (The only exceptions to this will be with the Glass Codes. Due to the difficulty of photographing them, drawings will be used instead of photos.)3. Calendars for the years 1964 thru 1972 will be included, listing the day of the month, day of the year, and week of the year, plus a guide explaining their use.4. And finally, at the end of this manual, will be a comprehensive list of parts that will reference the types of date codes commonly found on them, and when necessary, the approximate locations where these codes can be found. This book will decode Buick, Chevrolet, Oldsmobile and Pontiac date coded parts including; body panels, front end sheet metal, radiator core supports, all makes of glass (LOF, PPG, & DCL), DMI sport mirrors, radiators, all major cast engine components, vacuum trees, oil sending units (at least for the gauge equipped cars), water pumps, valve covers, oil pans, both varieties of clutch fans, Rochester, Holly, & Carter carburetors, starters, distributors, alternators, air cleaners, AC compressors, AC hoses, voltage regulators, steering boxes, master cylinders, power boosters, brake drums, calipers, brake rotors, car frames, front suspension center links, seat belts, radios, seat frames, bucket seat headrests, steering columns, Turbo-Hydramatic auto transmissions, Borg Warner T-10 and Muncie 4-speeds, Ford top-loader and Saginaw 3-speeds, rear axles, rims/wheels, spark plug wires, and probably a hundred other parts I haven't mentioned. (Please note; production codes for engines and transmissions will not be discussed.)The cost of the book shipped is $44.50. This includes $40.00 for the book, and $4.50 for shipping anywhere in the continental US. If you are interested in purchasing this book, you can send a check or money order to,Classic Car Interiors120 President Ave.Rutledge, Pa. 19070.The attachment at the top of this post shows the front cover.
