for I'm off early in the a.m. on at 2-week trip to be with extended family in TN, MS, and LA. I am not that familar with the 84(s) anyhow and would have to sort out which diagram to use and then go from there. In any event I would not start making major changes in the engine vacuum lines unless I first made a diagram or obtained the proper diagram which I then used to document the current state and then whatever changes I made along the way. This way you can return to a former state if needed. I'd love to following along with ya on this one but will likely have to wait until I return and read about what will be history by then.

See you in a couple of weeks!
Sam
