I got my factory assembly manual, chassis(?) service manual, and factory wiring diagrams at swap meets. There usually seems to be someone selling old documentation. The assembly manual was actually a photo-copied collection of the original.
Don't know if this helps you much or not - but it could be a start for you.
If you can't find them there, or don't want to wait for the next one try this link: listings.ebay.com/aw/listings/list/category1254/index.html
You can do a search on Chevelle, or other key words to hone the search down. They don't ALWAYS have them out there, but usually there are a few.
Madness takes it's toll, please have exact change.
