And the rest of the story...........
Jack, GM drawings do not generally show which supplier is supplying a given part for production. There were/are exceptions, which would be a part dedicated to a specific usage and or vehicle line.
It is much more detailed, but generally it went like this-----GM purchasing shows suppliers a drawing of a part they want and the suppliers tells GM purchasing how much it will cost. Purchasing then approves and designates one or more of the supplier to supply the part. Back in the 50s , 60s and early 70s GM purchasing was required to have at least three suppliers APPROVED for each part. Depending on the volume of the part, one or all three suppliers could be supplying said part.
BTW--- The part number in question, 219271, is actually a GM Standard Part from Current Product Engineering, Warren Michigan---which means that a Corvette Engineer went to the GM Standard Part book and said I want that one and he/she released it for a given application.
Now if you really want to know who manufactured a given part you could go to the RELEASE NOTICES which tells same. It is coded on the release notice and you would have to know how to break the code----and if you knew the code you would have to be killed because of course it is a closely guarded secret----no joke.
The GM Release Notices are the real deal for finding out most if not all of the information on ANY given part that went into production and or service. A part can and was released for may applications and could/would cross all Chevrolet Passenger and Truck vehicle lines. However, your chances of getting access to RN files is---none----0---zip---nada!
As far as getting drawings, your chances are slim to none. The Manufactures are required by their purchasing agreements to not show/give/duplicate, etc. the drawings to anyone. GM would never give access to the NCM or any other third party as you have suggested---sorry.
The EMI (GM's Licensed Reproduction Program) suppliers can only get drawings for the part they are manufacturing--they don't have carte blanche to the file rooms.
Unfortunately for you judges and NCRS types , GM is not in the business of manufacturing vehicles to be scrutinized in the way you want to. Trust me you guys already know more about these vehicles than they do.
