Back then you didn't want PS. Coz it was crap! No road feel whatsoever. Not until the RTS cars anyway.
I remember the first time in the '70's when I drove my mate's old man's 1970 ZD Fairlane with power steering.
They were a floater at the best of times but at highway speed the steering was so light that at the slightest touch you'd move six feet to the side, I swore on that day I'd never in my lifetime own a car with power steering.
My mother would have my sister move my car out of the way so she could get at dad's as she refused to drive mine because the wide tyres made it too hard to manoeuver, I have to be honest I'd hate to drive a car like that today as a daily.
