  • Bear in mind this is a conspectus of information on the 1966 Chevelle and not an all-encompassing, final word publication. The data presented here are as accurate as numerous GM publications, magazine articles, and knowledgeable Chevelle enthusiasts can make it. It is a fact that not even Chevrolet parts department parts catalogs can be kept 100% up to date 100% of the time.

  • From time to time owners will surface with some anomaly that cannot be explained such as ordering the Special Instrumentation option (RPO U14) and not receiving the tachometer that was part of the option or ordering the base 325hp engine in the SS396 series and having the car delivered with a 360hp open-element air cleaner. These anomalies cannot be explained with any rationale. The data contained on this Reference CD shows what should have been according to available Chevrolet documentation, not anomalies or factory errors that did not get caught in quality inspections. It should also be noted that many dealers would often change parts at the buyer's request after the car was received at the dealer.

  • It is also noteworthy to mention that even the AIM can be 'out of date' as revisions were constantly being made and options added or deleted throughout the model year.

  • Chevrolet often released Service Information Bulletins about replacement of items under warranty. Original, assembly line installed items would be replaced with regular service items. Naturally, these service items would usually differ from the original part and have a different part number.

  • Many part numbers shown on this CD are from an August, 1971 edition of a Chevrolet Parts & Accessories catalog I retrieved from the trash while working a Chevrolet dealer parts counter. It should be noted that the part numbers shown on this CD are part numbers we would look up to get you a GM authorized replacement part for your vehicle. Since this parts book was 6 years old at the time for the 1966 model year, some part numbers would have been superseded and/or the replacement part numbers may not have been the same as the original part numbers.

  • Part numbers should not be confused with casting or stamped numbers on a particular part. Sometimes the stamped number on a part was the same as the part number in the parts catalog, but not always.

  • Many part numbers differ between the AIM and the P&A Cat. due to revisions/changes in the part itself. The AIM often shows revised part numbers itself due to design changes before production. Part numbers from the P&A Cat. will be listed after part numbers from the AIM on the page. Be aware that even the numbers listed may have changed again after the publication of my P&A Cat. dated August, 1971 as the same part may have been used in later years.

  • As always, there are bound to be typographical errors, especially with part numbers. I have tried my best to be as accurate as possible but mistakes do occur. If you find one, please right-click the page, select Properties and send me the URL of that page for correction - and reread the paragraph above if you have a different part number. What is the date of the part number you find is in error?

  • This CD is not presented as a restoration guide with correct paint and finishes on specific parts but rather a conspectus of data to show how these Chevelles were built and the guidelines used to build them.

  • The photos on this CD are reprinted with owner's permission, where applicable, and credits are duly shown. Other photos were obtained from Internet auction sites and some submitted for inclusion on one of my many web sites over the years and are considered 'file' photos. When contacting the owners of the vehicles at the time (mainly dealers), those that did reply did not care if the photos were used as they were selling the car anyway and granted permission; others chose simply to not reply at all and those photos are not used.

  • Stamped numbers/letters on parts in some photos may or may not be original stampings and are shown only to show how and where these stamped numbers/letters should appear. Restamping original parts is very prevalent today to make some parts appear to be rare/original/valuable and one should exercise caution when purchasing or selling stamped parts.
