Sorry like a noob I posted this in the wrong place at first, in the what's it worth segment. I have a 71 'Cuda with manual steering that I want to convert to power steering. Besides the gearbox and adding a pump What other changes need to be made? And can any other body type gearbox work? Also converting from manual drum brakes to power disc. I have the spindles rotors power brake booster master cylinder and the portioning valve. Is there anything I missed.
