power to manual

Today i bought a manual steering box for my cuda, i installed it and the colomn's spline is to small for the boxes shaft. When the colomn is all the way foward it's like 2-3 inches away from the shaft. Is there a universal joint to put in there? The company i bought it fronm had a power box also and the car is an original power steering car. What should i do?
-Thanks
