I think your service garage is wrong. The 61-71 trucks never had a power box, just a power assist. The steering box and column were the same regardless of whether the truck had PS or not. Since your truck is even older I'm sure there wasn't a separate box for PS trucks. Your truck probably would take the same parts to convert to PS as the 61-71 trucks.Sweet1960D100 wrote: My problem is that it is very heavy for me on the steering.

Some have added integral power steering to their trucks using a power box designed for another vehicle. This requires fabrication but there is a kit in the works to add bolt on power steering to these trucks.
