I use to own a 69 A-100 PU that had power steering. While scouring junk yards for parts I ran across a A-108 window van with power steering. The motor was gone so I don't know if it was a V-8 but my 69 PU was a 225. The set up used a hydraulic cylinder that was clamped to the tie rod for power assist.
When seconds count...
The Police are only minutes away.
