    GM part numbers

    Where can I find a reproduction Corvette Parts & Accessories Catalog with the original part numbers for C2 years.

    Thanks,

    Sam

    There's no such thing available as far as I know. It would be nearly impossible to come up with, also. That's because part numbers changed over the C2 period. For example, a part that was catalogued in 1963 for a certain 1963 Corvette application might have been superceded by 1964 and another part number used. Even within the catalogues issued during a particular model year there may be some changes between editions.

    The AIM does provide a lot of the part numbers used during a particular model year. So, they are a good reference. The "gaps" are parts which were components of an assembly delivered to St. Louis and certain parts which are components of many RPO's.

      Only found in 2 places

      Joe's Library and mine. I recently showed Joe an obscure genuine GM part reference book that he had never seen before that was sorta like a Rosetta stone for identifying thousands of vendors that supplied parts to GM. I have never heard anyone refer to it by name ever. Not even remotely. Buy I made him swear not to tell anyone about it, or I would have to ....
      You need lots of books, even if they are an anathmema to some.

          Joe I have an original parts & Accessories catalog showing parts form 53 to 72. Would these part numbers in this catalog show the original part numbers, so I can identify a original part off say a 64?

            Re: GM part numbers

            I have one of those, and it's a useful reference. The only problem is the part number shown is the in effect at the time of publishing in 1972.

            For my car (70), it's about 95% accurate...for a 64, some part numbers may have changed two or three times since the car was built, but it will still have most of the numbers right. About the only place that will have correct part numbers for your car is the AIM, and that's sometimes not always true either when running changes are made.

            But, I expect what you are trying to do is correlate the AIM part numbers with vendor inventory now. The sad fact is, the GM part number at this time, is almost irrelevant...GM no longer stocks 99.9% of those old parts, and anybody else that's ever sold NOS or repro parts have pretty much depended on verbal descriptions rather than the old GM part numbers.

              They're on EBay all the time. They're interesting, but don't pay too much for them because they're only of limited use. The ones with edition dates close to the model year of your car will have the most part references. But 40+ years later, most of those part numbers will not be found in the GM system. The AIM will have many original part number references. The blowups in the parts catalogs used to be very helpful. But then the AIMs were discovered. The blowups in the catalogs come from the AIMs.

              What do you want the parts catalog for? To establish originality? Interchangeability? Usage in different applications and model years? The parts themselves and the part numbers changed over time. The catalog has some value in determining these things. But it is not the final word.

                mostly to To establish originality. I have a 64 and this part book is from 53 to 72. do you think that almost every part in this book will show originality?

                  Sam -

                  Not really. Many of the parts listed in the P&A books were released specifically for Service use, and have been superseded as "functional replacements" for original production-line parts, carrying different part numbers than the original production parts. Better references for determining "originality" are the Assembly Manual and the NCRS Judging Guide information.

                    Re: GM part numbers

                    That book you have will help. But it is not definitive. Remember that it was published more than 8 years after your car was built. Remember that Chevy changed these parts and the numbers. Sometimes a part sold in the Parts Dept. was different than that that was assembled on the car. Chevy changed numbers. Changed suppliers. Had more than 1 supplier. Made improvements in the design. But, yes, most of the parts listed in that book for your car would be original.

                    You can look up some part numbers. Google the part number. You'll be surprised at what hits you get. Look it up at "gmpartsdirect.com"

                      don't you think it is a good source for checking original parts and not as good for replacement parts on 63 through 67 corvetts

                        Some of the part numbers shown in the 1972 edition of the Corvette P&A Catalog will be original numbers used for a 1964 Corvette. Some will be supercessive part numbers for the original parts used on a 1964 Corvette. Some parts that were originally used on a 1964 Corvette and originally available in SERVICE will not be shown, at all, since they were discontinued without supercession prior to the date of publication of the catalog.

                          Hi Joe...My '65 edition P&A book (complete Chevy Line) also has p/n's that have been discontinued with the date and what p/n replaced it if any. Regards Frank

                            Yes, the older P&A Catalogs did have a history index. However, that only works if one knows the original part number to find the replacement part number; these were not a "2-way" index. Also, these indexes were not cumulative; they only list discontinuations and supercessions over about a 2 year period, ending, of course, with the publication date of the catalog.

                              Joe... yes you are correct. If I have the original part or p/n at least I can do some backtracking. The biggest problem with using the old catalog is coming up with the right Grp #. BTW, Thx for all your posts!!!! Regards Frank
