The easy way to convert a '63 or later C10 to PS, PB, etc., is to harvest a complete front end assembly, cross-member, etc. from any C10 that has disk brakes up to 81-82. Unbolt the '63 assembly, 16 bolts, bolt in the later model assembly, A direct swap requiring the elongation of two bolt holes to get them to line up.. An afternoon job. Once the swap is made then you can survey the new assembly for what repairs are needed.
We have done three of these swaps on '63-66 C10-20 trucks.
The best part about using the entire late model assembly, including the cross-member, etc., is that all of the geometry is set for modern disk brakes and power steering.
