Vacume Hose Diagram

[Bentblazer]

I usually hang out on the Blazer forum only because that is what I have, but met some one last night that says he has a 72 with a factory 402 BBC with with less than 35000 actual miles. The problem is that the truck was stored several years before he aquired it, and nearly a year ago he decided to replace all of the vacume lines and didn't finish before moving and has forgotten the routing of them. Sinse he does not have a pc I thought I would help, checked the search function a could not find a diagram for the hoses. Does any body have or know where I can find a diagram for these lines? If I can get this for him I plan on taking pics and posting, he says its a beautiful truck and won't believe the condition we'll see! Thanks for any help
