I would Keep It Simple Sam and search for a 742 (preferred) or 741 sure grip which would from the factory both have the highly desired clutch type sure grip in the ratio you desire for your app. if the pinion yoke does not match your driveshaft there is a combo ujoint to easily solve that minor dilemma. EDIT there is also a 6.20 742 gearset (I have one)
