"both run around the back of the cover to a "tree" of three valves/switches that mount directly to the valve cover."

This is where the non broken ends run to.

Is there a vacuum system diagram on the radiator sight shield??? Usually there's other info there also, sparkplug type, gap, etc.. If not, you're going to have to get a repair manual, Chilton, whatever to check it out..

I dont want to sound like I dont appreciate your time to respond to my problem, but I cant find a diagram on the truck or in the book.
All the book says that I have been able to find is that I need to mark all vacumm lines for correct connection when Im putting everything back together.
I think I will try two things.
1. Find someone that has a similar truck in my area, give them a buck to look under the hood, or
2. Hook both lines to the vacuum tree on the upper intake manifold and see if the truck starts and or runs better than it did.
Since I can find no other unused vacuum ports on that side of the engine, Im seriously thinking that they must go to the vacuum tree, and that my buddy couldnt figure out where they broke from so he just put caps on the ports on the tree that didnt have anything going to them.
I would ask him but he has moved out of town with no forewarding address.
