I'm rebuilding my steering box (70 cuda manual box) I called steer and gear to see if they sold the parts or just do rebuilds. They said they will sell the parts but they size the balls in worm gear and bearings and fix some things in the case that will be worn. Does this sound legit or just a sales pitch. They also said the 20:1 gear will make the car very hard to turn and recommend not using it. Anybody used steer and gear or have any opinions on the 20:1 gear.
