the ez but expensive way is to find a 55-59 gmc 1/2 ton to 1ton truck with power steering and use that. it has a speacial saginaw box that will bolt to the three holes where the original steering gear bolted. On a chevy, the top of the frame may have to be cut out for clearence. These boxes are very hard to find, and you can expect to pay a lot of money if you are lucky enough to find one. the steering column needs to be changed as well. the column is coupled to the steering gear with a modern stile flex coupler.
