DIY installation of hydraulic power steering to Suzuki SJ410

How to adapt a complete system of hydraulic power steering, with mechanical pump driven by belt, in a Suzuki Santana SJ410 1986. The system is used by the Suzuki Jimmy and is bought in a scrapyard.
It consists of a Jimmy power steering box that fits perfectly into the Suzukis Santana and Samurai frame and an original Suzuki Jimmy pressure pump, but which needs to be crafted to be bolted to the F10A engine block of the SJ410. (1000 c.c. engine)
I explain in detail the manufacturing process of the necessary double pulley and the rest of the pieces.
