Factory stripe/molding placement book?

[Irish1941]

Years ago, I worked at a dealership in the body shop and we had a book that gave dimensions for replacing stripes, emblems and moldings on the body but can't find any reference to it online. It had all the measurements as per oem specs. I can't even remember what it would be called...
Anybody seen one or have one? Specifically the '89-91 R,V trucks.
Looking to replace all trim when my truck goes in for paint in a few months but want to get in the right spot. Don't really trust the body shop to put it back right.
Thanks very much in advance!
