you need to swap the vacuum booster out for the hydraulic one, it should hook right up to your brake pedal. Master cylinder may or may not need changed, new master cylinder can be had for under $30 usually. Remove the high-pressure line you now have, hook up the two pressure lines that come with the hydraulic booster (one goes to PS pump, the other to the steering box), T-ee the return lines from the booster and the box together, and that's about it.
