The big boat needs some help turning. I know the Pontiac was a GM product but did it share any parts from other GM cars around the same age that had power steering that could be bolting in? Example: would a 50's Caddy have the same front end and thus use the same parts? If not what is a popular kit that others have come up with? Plumb the stock box, change out to a after market power rack, add a steering ram?
