71 Dodge Dart Swinger in England

Ford 9" do not have a pinion snubber since they werent designed for this application. You will prob need to install either cal tracs bars, or some other sort of traction bars if you plan to drive it hard to prevent spring wrap up.

The pinion snubber is a rubber bumper on a bracket mounted on the center gear housing that prevents the nose section of the diff from rotating up too high on hard acceleration. It hits on a reinforced spot on the rear floorpan.
