Ford Ranger rear end fit '71 Dart?

If you take apart the brakes on a little old lady's car, the fronts and rears are worn evenly. But a high performance car that experiences extremely hard braking will wear out three sets of fronts to every one set of rears because the front dives and weight is transferred from the back to the front. My Fiat 124 had a link from the rear axle to a brake proportioning valve that reduced pressure to the rear brakes depending on the distance from the axle to the frame.
