gm cross reference ( obsolete parts)

OK I am trying to find the right description for the following part numbers searched parts wiki, wild about cars, even paid the full membership to the historical society
its the fasteners for a 4 speed console 64-69
9420082 ( screws for plate)
9420129 ( found 8-18 x 1/2)
9418653 screw through hinge to top plate
148558 screw through hinge to base
9421193 screw to mounts
9419320 ( found #10 x 3/8)

is there a cross reference anywhere else? Any help would be greatly appreciated

Some hardware can be tracked through the AMK Restoration parts site. Most GM hardware items were listed in separate catalogs called GM Standard Parts. They included screws, nuts, bolts, cotter pins, clips, ball bearings, molding nuts...a lot of hardware that was used across the BOPC lines. Every year there was a new one, later years they included metric stuff. Even the numbers in those catalogs were superseded or discontinued multiple times. Many regular GM parts catalogs had a few pages of hardware, hoses, bulbs...listed among the parts. Typically, those listings are at the end of sections 8.00 or 9.00. Exact correct hardware numbers, aps, and sizes are really hard to find. It can take hours and hours to find one item. The AMK catalog is one of the best for finding that stuff. They will tell you the size, finish, hardness and sometimes aps. You can get on there online. Something like this catalog, although this is Canadian.

hoping

Well I grabbed these two sets of Manuals hoping they will help in Identifying all the hardware I have been cleaning up, and help Identify a ton of parts I bought in a lot that came in tubs...

I'm afraid that you are going to find that the April 1983 printing is not going to be of much value. As Olds dropped or superseded part numbers in the parts system, the revised parts books no longer listed them. As an example, if you look at BBO cylinder heads in this edition, you will only find two part numbers listed, the J heads and the K heads. The K heads are shows as the superseded P/N for all performance applications - basically they replaced the D, F, and H heads. The J heads are shown for all other applications. Most part numbers from the 60s and early 70s just aren't listed in this edition. The book only covers the parts actually available in the parts network when it was printed.

Part numbers were superseded from the day of production. Basically you want a book printed as close to the year of the car you care about as possible. There is a Jan 1972 edition posted on line. Even that has superseded numbers. For example, it only shows the 71-72 front fenders with the "bumps" and lists those as the correct parts for 1970 also, since they superseded the "flat" fenders.

I should add that the "ground truth" for the correct part numbers for a specific year and model is the Product Information Manual (aka Assembly Manual) for a specific year and model. These are the engineering drawings used to assemble the car. Even these have been modified over the production year, so all you get are the last versions of the part numbers. If something changed mid-year (for example, the hood latch on the 1968 Cutlass line), only the last design will be shown. Unfortunately you frequently need to piece together this change information from the PIM, the Parts Book, the Service Guild bulletins, and the engineering orders. Another example is the use of the cast iron t-stat housing with the metal J tube as opposed to the rubber bypass hose. The engineering order attached here documents the change and retrofits.

I'll also add that Olds used EOs like this for every change on the assembly line, which is why I throw the BS flag when someone claims that a one-of-none car is real "because anything was possible".

Another resource that could help is the monthly Price Schedule. It has a column showing which other GM brands used the same part number. That could help you find the stuff in a junkyard, or at a show of the other brand.

So long as you are not looking for 1972 model year parts.

Dec 70 will cover the first part of the 1971 model year, obviously. That would be a great book to have.
