Body panel assembly manual.. does it exist?

For what exactly?
What I'm interested in at this point is a-pillar inner-outer panels, and where they join to the cowl and roof pillar. Later it'll be floor and rockers. Yeah, working on a Wisconsin rust bucket '69 notch.
Just wondering if there's any kind of body manual that show how the various panels/parts go together.
I know it's easy enough to figure out sanding or grinding things down to see, but the car isn't really accessible right now. Just be nice to figure out a plan of what order I need to do things in.
