Sorry for the noob response. I am familiar with hydroboost where there is either a gas accumulator or electric motor as backup. Since I don't have a donor, I'm going off of diagrams and random pics that indicated an electric motor backup for the hy-power option, whereas the dual-power option has the traditional vacuum booster behind the hydro-boost. I'm still learning - if you have pics of the setup under the hood, that would be awesome. So it goes like this:

pedal-rod-hydraulic booster-M/C-balance valve-wheel cylinders. Guess I need to hit a junkyard. There's a rod in between the booster and MC right?
