The assembly manuals have most of the stuff in it. Probably 95% correct. the problem is that the assembly manuals that are available are a snapshot in time someone got permission from GM (I assume) to copy a manual like the 69 and that then becomes the gospel. But I would bet that the 69 AM that most people have is one that was isssued around June of 1969, since it does show that the chambered exhaust has been cancelled (5/29/69) but it doesn't show the the Z28 exhaust system that uses the resonators that came after the chambered systems.
The AMs don't have all the engineering change orders that were issued through out the year identifying this part was changed from this to that because of this. So people begin to believe that if part number X is listed in the AM then it must be the right part number but that is not always true. The other problem is that alot of the part numbers listed in the AMs are assembly numbers which contain a lot of little parts. The front steering system is a good example, there is a single part number for everything from the left tie rod end to right tie rod end. You need to dig into a dated (1969) parts manual, not the 1983 version to dig out the individual pieces.
