These new steering boxes are manufactured using the highest quality all new components - sector, recirculating ball worm and nut, bushing and roller bearings.  Even the casting and cap are new! (this also means no core charge is required!) 

This unit is dimensionally interchangeable with the original, but all new parts will bring back performance steering and handling to your vehicle.  Of course, the ratio is the quick 16:1 design preferred by enthusiasts.
