If the rack & pinion unit bolts to the body, there are dangerous bump steer issues involved when negotiating turns. If it bolts to the axle, the slip joint required to connect the pinion gear to the steering column has a nasty habit of hanging up and/or breaking, leaving you with either no steering at all or unpredictable stiffness at the worst possible time. You owe it to yourself to become very familiar with the principles of steering and suspension geometry before undertaking the kind of project you're considering, not betting your life (and mine) on someone who has something to sell you. Either way, you become a hazard to the rest of us out there on the road with you. If you "take it anywhere" please do it on a trailer!
