Does the 1975 Datsun 280z have power steering?
280Zs didn’t come with power steering! The 1979 ^ 280ZXs had two types of power steering both of which would be difficult if even at all possibele to put in a S30 because of the location and design of the components. The first 280ZXs had worm and roller power steering. I guess you could count those out because that would be a step backwards in my opinion. I don’t know when the changeover took place but the later 280ZXs did have rack and pinion power steering but the rack is located behind the front axle unlike the 280Z where it is in front.
