Not exactly the answer, but....
Small cars don't need power steering.
I removed my power steering completely years ago and made a light weight aluminum block off cover
for under the car. It is a myth that power steering fluid lubricates the steering rack.
Otherwise when you replace a rack boot, fluid would spill out on the ground.
One more thing out there is one more thing to buy and one more thing to break.
No one pays you even one dollar more for a car that is collector-car original.-Bob
