I think I would think twice about using 2 hydrovac's. They are simple
vacuum boosters and I think they would be hard to get balanced (front
circuit to back circuit), fronts or back doing all of the work. I could be
wrong but something just doesn't sound right. If you really want a 2
circuit power brake system why not use a newer truck set-up. My .02 cents.
