Has anyone seen a materials list of all of the vacuum lines on a non-California stock 403? Approximate total length and diameters?

I want to replace all my vacuum lines. I can do the obvious and catalog it myself, but I thought if someone else had documented it already I could save myself a lot of labeling/measuring time, plus I am at work and could grab the materials on the way home,and maybe check one more item off the to do list. Thanks in advance.

These may help if you dont already have them.
The first is the GMC Maintenence Manual and the second is the 77-78 w/403 supplement.
I've downloaded both and they have been a great help.
