Good day 1958 Viking. Another method of power steering that may be worth using is a modern electric assist power steering system.
Many new cars & trucks now use this method. Aftermarket systems are being used by many hot rodders and rock crawlers. Used parts for conversion are showing up in the salvage yards.
The electric assist will mount under the dash of your truck. You just need to cut the steering column and put the new actuator between the top and lower parts of the shaft. Some have a electric control box but it is small and will also mount under the dash.
A new aftermarket unit is affordable and a used system is cheap.
Have fun. Howie
