Power steering interchange help

anyone know if a power steering box from a 64 chevelle will fit a 58 full size chev ?

 

car or truck?

 

If the Chevelle uses an integral power steering box, then no, it will probably will not work. 58 Chevys used a booster cylinder, and had nothing to do with steering box. However, considering Pontiac used a similar frame to the Chevy, then it might be possible to graph the Chevelle box to the Chevy. Pontiac I believe had the integral type box.
