I am rebuilding a 1951 Chevrolet pickup and adapted a power steering unit to it. The steering column did not align exactly with the power steering unit. I researched u-joints and found exactly what I needed. The steering worked out very well thanks to the folks at Speedway Motors and their suggestions and help.
